Functionally, it is comprised of a VHF Low Band Receiver Tray (1265-1100) and a 20 Watt VHF High Band Upconverter/Amplifier Tray {1355-1010 (Low Band), 1355-1011 (Mid Band) or 1355-1012 (High Band)}. The Receiver Tray receives the Low Band VHF Channel Input at Jack (J1) and converts it to an Internally Diplexed Visual + Aural IF Output (+0 dBm) at J4. The Visual + Aural IF output of the Receiver Tray at J4 is fed to J2 the IF Input Jack for the 20 Watt VHF High Band Upconverter/Amplifier Tray. The Upconverter Section of the Tray mixes the IF with an internally generated L.O. to produce the VHF High Band Channel Frequency Output. The signal is amplified and filtered in the Amplifier Section and directed to J4 the RF Output of the Tray. This output connects to the Antenna for your System. Jack J7 located on the back of the Upconverter/Amplifier Tray is a 37 Position "D" Remote Interface Connector which provides the Operator with a connection for Remote Monitoring and Operation of the Translator. This manual provides the Technical Specifications of the Translator, along with the Circuit Description, Alignment Procedure and the Schematics, Block Diagrams, Interconnects and Replacement Parts Lists necessary for the proper operation and maintenance of the 117B.

Axcera-117B FCC Type Acceptance Report Parts List/Tune-up Info September 2002 7-1 7. PARTS LIST/TUNE-UP INFO 7.1 Parts List The translator, can be subdivided as follows: Receiver Tray: -VHF filter -Dual stage amplifier board -Channel oscillator Assembly -Channel oscillator multiplier board -Downconverter/amplifier board -IF filter/ALC board -SAW filter amplifier board -Power supply board 20-Watt Upconverter/Ampliifier Tray: -Channel oscillator assembly -Channel oscillator multiplier board -Filter/mixer board -ALC/AGC board -Linearity corrector board -Filter amplifier board -VHF high-band driver board -VHF high-band amplifier board -Low pass filter -Trap filter board -High-band VHF coupler board -Visual/aural metering board -Transmitter control board -AGC control board -Power supply board -Switching power supply 7.2 Tune-up Information The 117B translator was aligned at the factory and should not require additional alignments to achieve normal operation. The UHF/VHF Receiver Tray w/(Optional) Frequency Correction selects the desired UHF or VHF On Channel Input Signal and converts it to a Combined IF Signal of 45.75 MHz Visual + 41.25 MHz Aural. The Tray also has provisions for a Frequency Correction Option that consists of a VCXO Channel Oscillator Assembly with a PLL Circuit which maintains an exact IF Output Frequency, over the capture range of the PLL circuit, even if the Input UHF or VHF Frequency may vary. 7.2.1 RF Input Signal Path (Receiver) The RF Input to the Tray, (-61 dBm to -16 dBm in Level), is fed through J1 for 50Ω to (A7) the input 50Ω Filter, DC Multiplexed (1035-1204 UHF, 1035-1902 VHF LB or 2065-1024 VHF HB) or through J5 for 75Ω to (A7) the 75Ω input Filter, DC Multiplexed (1035-1207 UHF, 1035-1903 VHF LB or 2065-1023 VHF HB), which is of a double tuned design that is adjusted to the desired Input UHF or VHF Channel Frequency. Note: If the input signal is Axcera-117B FCC Type Acceptance Report Parts List/Tune-up Info September 2002 7-2 greater then -25dBm, an attenuator should be used to limit the level to -25dBm. +12 VDC, for use by an (Optional) external Preamplifier Assembly, connects to the filter through F1 a 1 Amp Fuse. This +12 VDC is DC Multiplexed onto the input signal cable from the Preamplifier. DS1 a Red LED located on TB1 in the Tray will be lit if the +12 VDC is present on the input cable. If a Preamplifier is not used, F1 should be removed and DS1 should not be lit. The signal is next amplified +12 dB to approximately the -49 to -4 dBm level by a low noise amplifier located on (A8-A1) the Dual Stage Amplifier Board (1227-1501) that is contained in (A8) the Dual Stage Amplifier Assembly (1227-1503). The board has approximately +13 dB or +26 dB of gain, depending on whether Jumper W1 on J5 is in place. The signal is then filtered in (A9) a Channel Filter (1007-1101 UHF, 1034-1202 VHF LB or 2065-1000 VHF HB) and then applied back to (A8-A1) the Dual Stage Board where the same amplification takes place. Jumper W1 on J7, located on the Dual Stage Board, should be removed if the Receiver Input level is greater than -40dBm. The output is connected to (A10) the Downconverter Amplifier Assembly (1227-1505) that contains (A10-A1) the Downconverter Amplifier Board (1227-1502). The RF, at the -47 dBm to -2 dBm Level, connects to the "R" Input Jack of the Mixer Z1 located on the Downconverter Amplifier Board. 7.2.2 Local Oscillator Signal Path (Receiver) The Local Oscillator Signal is derived from a cut to channel crystal mounted in an oven that is factory set at 45° C. The Oscillator operates at 1/8 for UHF, 1/4 for VHF High Band or 1/2 for VHF Low Band of the desired local oscillator frequency. The crystal is mounted on (A4-A1) the Channel Oscillator Board, Dual Oven (1145-1201), that is part of the Channel Oscillator Assembly (1145-1202). The oscillator circuitry is a modified Colpitts design operating in a separate oven set at 50° C. for improved stability. If the Frequency Correction Option is purchased, the VCXO Channel Oscillator Assembly (1145-1206), which contains the VCXO Channel Oscillator Board (1145-1204), is used in place of the standard Channel Oscillator Assembly, and an AFC voltage from the PLL circuit maintains the frequency of the VCXO. The output of the Channel Oscillator is connected to the (A5-A1) the x8 Multiplier Board (1227-1002) for UHF, the x4 Multiplier Board (1227-1525) for VHF HB or the x2 Multiplier Board (1227-1524) for VHF LB, which is located in (A5) the Multiplier Enclosure (1265- 1125). The proper multiplier board takes the output of the Channel Oscillator (+3 dBm) and multiplies it eight, four or two times by a series of three, two or one x2 Broadband Doublers (2x2x2 = x8), which produces the L.O. signal on the desired frequency needed for the upconversion process. The signal is then amplified to the +16 dBm level. A sample of the multiplied L.O. Signal is fed to a detector circuit which lights the Green LED DS1 that indicates that the L.O. is present at the Output Jack J2 of the Multiplier Board. This Green LED is seen through a hole the lid of the Multiplier Assembly and is an indication, when lit, that there is a signal present at the output of the Multiplier Board. The L.O. signal is filtered in (A6) a L.O. Filter 1007-1101 UHF, 2065-1000 VHF HB or 1034-1211 VHF LB) and then sent (+15 dBm) to J2 on (A10-A1) the Downconverter Amplifier Board. The L.O. Input to the Downconverter Amplifier Board is connected thru a 3 dB matching pad to the "L" Input of the Mixer (Z1) at a +12 dBm level. 7.2.3 Combined IF Signal Path (Receiver) The L.O. and the RF signals are mixed in the Mixer Stage of the Downconverter Amplifier Board to produce the desired IF difference frequency at -55 dBm to -10 dBm in level, depending on the RF Input Level. The Combined IF Signal is routed to (A11-A1) the IF Axcera-117B FCC Type Acceptance Report Parts List/Tune-up Info September 2002 7-3 Filter/ALC Board (1227-1504), which is mounted in (A11) the IF Filter/…
