Refer to the block diagram of the FFPA8689-120 FFPA, Figure 4. 4.2 RF Input Signal The maximum input signal for all carrier frequencies should not exceed the limits specified in the electrical specifications. The input VSWR should be 2:1 maximum (or better). 4.3 RF Output Load The load impedance should be as good as possible (1.5:1 or better) in the operating frequency band for good RF power transfer to the load. 4.4 System Functional Description The FFPA8689-120 amplifier is a linear, feed forward power amplifier which operates from 869 to 894 MHz with a rated output power of 120W total (average). The amplifier produces better than 65 dBc intermodulation products. The amplifier operates from a 24-28 vdc input power source, and provides a rear I/O interface to report all faults and alarms. The front panel of the amplifier contains the DC ON/OFF switch, and the status LEDs. PM/8689120R1.DOC-991101 1999 - MPD TECHNOLOGIES, INC. 19 MPD TECHNOLOGIES, INC. Model FFPA8689-120 The amplifier is comprised of the following:
Carrier Cancellation Main/Error Driver Amplifier Main Amplifier Error Amplifier DC/DC Function Microprocessor Control Loop Processor Pre-distorter The main amplifier employs class AB amplification for maximum efficiency and low intermodulation distortion. The error amplifier and main/error driver amplifiers operate class A mode. The input RF signal is amplified by the carrier cancellation and then split into a signal and a reference path. The signal path is sent through the main driver amplifier where the amplitude and phase are modified based on the reference signal, and then amplified by the main amplifier. The signal is coupled off to the carrier cancellation where the 180 degree converted amplified signal meets the reference signal. At this point the combined signal which has a canceled carrier (called the IMD signal) is sent to the IMD leg of the feed forward amplifier. The IMD signal is sent to the error driver amplifier and error amplifier. The signals amplitude and phase are adjusted from the input by the loop processor. The signal is re-injected into the main amplifier output signal and the combined signal yields intermodulation suppression of 65 dBc minimum. 4.4.1 Main Amplifier The main amplifier operates class AB that provides approximately 22 dB of gain over the operating frequency band of 869-894 MHz. The main amplifier operates on 27.0 VDC, and utilizes 15V DC to derive bias. The main amplifier is directly mounted to the heatsink. Within the main amplifier are the temperature sensors, which detect the baseplate temperature. 4.4.2 Error Amplifier The main function of the error amplifier is to amplify the distortion products generated by the main amplifier, so they can be canceled when the signal is coupled onto the main signal at the output of the amplifier. The error amplifier operates class A, has 47 dB of gain, and produces a 2W output. The amplifier operates on 27.0 VDC, and PM/8689120R1.DOC-991101 1999 - MPD TECHNOLOGIES, INC. 20 MPD TECHNOLOGIES, INC. Model FFPA8689-120 utilizes 15V DC to derive bias. The error amplifier is mounted to the heatsink, and utilizes an output circulator to protect the error amplifier output. The load port of the circulator is connected to a detector to monitor reverse power. This analog voltage is monitored by the microprocessor to determine the safe reverse power levels during operation. If the detector level is too high (greater than a 3:1 mismatch), the amplifier goes into a fault mode and bias is turned off for protection. 4.4.3 Amplitude and Phase Adjustment The two loops are controlled via the microprocessor through the main and error driver amplifiers. The amplifiers include a vector control circuitry to adjust amplitude and phase of the RF signals. The microprocessor controls the amplitude and phase adjustment for the two loops. The loop processor responds to the amplitude and phase of the IMD loops. 4.4.4 Amplifier Module Cooling The amplifier is cooled via forced air through the heatsink. Two rear fans are used to draw air through the heatsink. The fans are field replaceable and are monitored for fan faults. 4.5 Power Distribution The amplifier employs a DC/DC converter to regulate the amplifier sub-circuits to the required voltage, based on a 22-29V DC input. The power supply board converts the input voltage to +/-5V, and +/-15V used by the loop processor and microprocessor. 4.6 Intermodulation The FFPA8689-120 amplifier is designed to deliver 120W average power, multicarrier signal, operating over the passband of 869-894 MHz. 4.6.1 Two Tone Intermodulation When measured with two equal CW tones, spaced anywhere from 30 kHz to 25 MHz apart, and at any power level up to the peak power, the third order intermodulation products are below -65 dBc. 4.7 Alarms The amplifier reports various alarms, indicated via a front panel LED, and via the I/O connector on the rear.
