The OTX02-250 transmitter consists of the following assemblies (refer to Figure 3): 1. Upconverter Assembly – for converting the incoming VHF signal to microwave. The upconverter assembly contains all components necessary for upconversion, i.e. local oscillator, mixer, as well as bandpass and notch filters. 2. Predistortion Linearity Assembly – Transmitter linearity is significantly improved by the addition of a linearity enhancement circuit to the microwave power amplifier. The better the linearity, the lower the composite triple beat (CTB) distortion. 3. Power Amplifier – The amplification is accomplished with minimum distortion by a state of the art Gallium Arsenide FET microwave power amplifier with an established field reliability record. The power amplifier is protected from failure due to overheating by an internal temperature sensor. The sensor circuit automatically switches off the amplifier D.C. power when the amplifier temperature exceeds 158° F (70° C). 4. Power Supply System – The OTX02-250 utilizes two AC/DC power supplies. One provides +12 VDC power to the power amp, and the other provides +12 VDC power to all other devices. 5. Monitoring and Diagnostic Circuits –The output of the OTX02-250 can be continuously monitored without interruption of service with a standard field strength meter. Diagnostic DC voltages can also be continuously monitored via a multipin connector. Both test points are located on the bottom of the OTX02-250. …

Some examples of operational descriptions include: 2.1 General Description The MMDS Outdoor Transmitter OTX02-250 (shown in Section 4.0, Figure 3) is a solid- state broadband transmitter that converts VHF input signal of 222 to 408 MHz to a microwave signal of 2.5 to 2.686 GHz. The OTX02-250 transmitter consists of the following assemblies: 1. Upconverter Assembly – for converting the incoming VHF signal to microwave. The upconverter assembly contains all components necessary for upconversion, i.e. local oscillator, mixer, as well as bandpass and notch filters. 2. Predistortion Linearity Assembly – Transmitter linearity is significantly improved by the addition of a linearity enhancement circuit to the microwave power amplifier. The better the linearity, the lower the composite triple beat (CTB) distortion. 3. Power Amplifier – The amplification is accomplished with minimum distortion by a state of the art Gallium Arsenide FET microwave power amplifier with an established field reliability record. The power amplifier is protected from failure due to overheating by an internal temperature sensor. The sensor circuit automatically switches off the amplifier D.C. power when the amplifier temperature exceeds 158° F (70° C). 4. Power Supply System – The OTX02-250 utilizes two AC/DC power supplies. One provides +12 VDC power to the power amp, and the other provides +12 VDC power to all other devices. 5. Monitoring and Diagnostic Circuits –The output of the OTX02-250 can be continuously monitored without interruption of service with a standard field strength meter. Diagnostic DC voltages can also be continuously monitored via a multipin connector. Both test points are located on the bottom of the OTX02-250. 6. VHF Processor Module – The VHF input to the transmitter is sent to the VHF Processor Module. This is a level set attenuator. The VHF signal is then sent to the upconverter mixer. 7. Low Noise Amplifier with AGC – The OTX02-250 has a LNA with a built in attenuator circuit. The attenuator is controlled by a composite AGC module. The output of the OTX02-250 is keep at a constant level regardless of ambient temperature changes 8. Fan Assembly – The OTX02-250 is cooled by a +12 VDC fan controlled by a thermostat mounted on the heat sink. The OTX02-250 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: JXZOTX02-250 Type Acceptance Report 9/4/02 8 Proprietary The OTX02-250 Transmitter consists of the following circuits or modules: 1. Upconverter Section 2. Microwave Predistortion Assembly 3. Power Amplifier 4. Power Supply System 5. Diagnostic Circuits. 6. Low Noise Amplifier With AGC 7. Fan Assembly In addition, microwave isolators and filters are used as necessary to ensure the stability and purity of transmitted signals. 2.3 Upconverter Section The Upconverter Section is comprised of the following major functional circuits or modules: 1. Hybrid Local Oscillator 2. Upconverter/ Mixer 3. Filter Assembly 4. VHF Processor Module Hybrid Local Oscillator - The local oscillator consists of a crystal oscillator, frequency multiplier, and a band pass filter all encapsulated in solid 6061-T6 aluminum. The frequency of the oscillator is 2278 MHz. The frequency stability of the oscillator is .0005%. The output of the local oscillator provides pump power to the signal upconverter. The local oscillator is powered by +12 VDC. Upconverter Mixer - The translation from VHF to microwave frequencies takes place here. The mixer is also called an "upper sideband upconverter". The desired output of the upconverter is a signal at a frequency, which is the sum of the local oscillator, and VHF input frequencies. The upconverter also generates unwanted signals that have to be filtered out, among them the "lower sideband", LO leakage, and others. Filter Assembly - There are two filters. The group bandpass filter is tuned to pass the upper sideband. The notch filter is tuned to attenuate the local oscillator leakage without affecting the output signal. VHF Processor Module – The VHF signals are sent to the Processor module first. The processor changes the impedance of the VHF signals from 75 ohms to 50 ohms, and the processor has a level set attenuator so minor level changes can be made. 2.4 Microwave Predistortion Network Predistortion Linearizer Network enhances the linearity of the amplifier by generating distortion products equal in amplitude but with opposite phase to those generated in the power ampli…
