The ITX02-2000 transmitter consists of eight assemblies: 1. Driver Chassis - for converting the incoming VHF signal to microwave. The Driver chassis contains all components necessary for upconversion, i.e. local oscillator, mixer, as well as bandpass and notch filters. 2. Power Amplifier - input signal is amplified to a maximum level consistent with the Carrier to Composite Triple Beat (C/CTB) specification by state of the art GaAs FET microwave power amplifiers in a parallel, power-quadrupling configuration. The power amplifiers are protected from failure due to overheating by an internal temperature sensor. The sensor circuit automatically switches off the amplifier when the amplifier temperature exceeds 167 degrees F (75 degrees C). 3. Power supply system - a redundant 12 VDC system consisting of three current sharing modules with hot-plug replacement capability. Each module has an 84 Amp capability. Only two modules are required to run the system, making the third one a built-in spare. A +5 VDC voltage regulator is used to power the power amplifier TTL circuit. The Driver chassis and fans are powered by the +12 VDC power supply. 4. Monitoring and Diagnostic Circuits - To facilitate operational monitoring and diagnostics of: VHF input, VHF output, D…

Proprietary FCC ID: JXZITX02-2000 Type Acceptance Report 6/20/03 2 Proprietary 2.0 OPERATIONAL DESCRIPTION This section should include any operational or technical descriptions regarding how the device operates, is modulated, or meets specific requirements. Some examples of operational descriptions include: 2.1 General Description The MMDS Indoor Transmitter ITX02-2000 (shown in Section 4.0, Figure 3) is a solid- state broadband transmitter, which converts a VHF input signal of 222 to 408 MHz to a microwave signal of 2.5 to 2.686 GHz. The ITX02-2000 transmitter is comprised of the following sub-assemblies: 1. Driver Chassis - for converting the incoming VHF signal to microwave. The Driver chassis contains all components necessary for up-conversion, i.e. local oscillator, mixer, as well as band pass and notch filters. 2. Power Amplifier - input signal is amplified to a maximum level consistent with the Carrier to Composite Triple Beat (C/CTB) specification by state of the art GaAs FET microwave power amplifiers in a parallel, power-quadrupling configuration. The power amplifiers are protected from failure due to overheating by an internal temperature sensor. The sensor circuit automatically switches off the amplifier when the amplifier temperature exceeds 167° F (75° C). 3. Power supply system - a redundant 12 VDC system consisting of three current sharing modules with hot-plug replacement capability. Each module has an 84 Amp capability. Only two modules are required to run the system, making the third one a built-in spare. A +5 VDC voltage regulator is used to power the power amplifier TTL circuit. The Driver chassis and fans are powered by the +12 VDC power supply. 4. Monitoring and Diagnostic Circuits - To facilitate operational monitoring and diagnostics of: VHF input, VHF output, Driver RF output, and Transmitter RF output. diagnostic DC voltages can also be continuously monitored with the built-in meter on the Meter Panel. 5. On-Delay Timer Assembly - Delays power to the amplifier. This is done to avoid a big current surge when the transmitter is first turned on. 6. Internal Down-converter - For ease of monitoring the Transmitter’s output, a down- converter has been mounted inside. The down-converter takes a sample of the output and converts it to VHF. This VHF output signal can then be measured with a Field Strength Meter or a TV monitor. The ITX02-2000 transmitter can be equipped to operate on either 120 or 240 VAC at 50 or 60 Hz. This option is specified by customer request, and each unit is shipped according to this specification.

Proprietary FCC ID: JXZITX02-2000 Type Acceptance Report 6/20/03 4 Proprietary The ITX02-2000 Transmitter consists of the following circuits or modules: 1. MMDS Transmitter Driver 2. Power Amplifier 3. Power Supply System (three +12 VDC current sharing modules and one +24 VDC power supply) 4. Monitoring and Diagnostic Circuits - connectors and switches. 5. On-Delay Timer Assembly. 6. Internal Down-converter. In addition, microwave isolators and filters are used as necessary to ensure the stability and purity of transmitted signals. 2.3 MMDS Transmitter Driver The MMDS Driver is comprised of the following major functional circuits or modules: 1. Local Oscillator (LO) 2. Up-converter/Mixer 3. Filter Assembly 4. Microwave Low Noise Amplifier 5. DC Diagnostics 6. Power Supply Local Oscillator (LO) The microwave local oscillator is a crystal oscillator and frequency multiplier encapsulated in a single enclosure. The output of the LO provides pump power to the signal up-converter. The LO is powered by a +12 VDC power supply. The long-term frequency stability of the oscillator is 5 parts per million per year. Up-converter Mixer The translation from VHF to microwave frequencies takes place here. The mixer is also called an "upper sideband up-converter". The desired output of the up-converter is a signal at a frequency, which is the sum of the local oscillator and VHF input frequencies. The up-converter also generates unwanted signals which have to be filtered out, among them the "lower sideband", LO leakage, and others. Filter Assembly There are two filters. The group band pass filter is tuned to pass the upper sideband. The notch filter is tuned to attenuate the local oscillator leakage without affecting the output signal. Microwave Low Noise Amplifier A Low Noise Amplifier accomplishes the amplification with minimum distortion. Proprietary FCC ID: JXZITX02-2000 Type Acceptance Report 6/20/03 5 Proprietary DC Diagnostics Circuit Certain test points in the transmitter can be monitored externally at the Remote Monitor output multi-pin connector on the front panel. These DC diagnostics are connected to the output connector through a signal conditioning circuit. The signal conditioning circuit is a network of resistors that provides s…
