EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation Table 2 Power Amplifier Circuitry (Continued) Circuit RF Combiner/Peripheral Module Description • Contains a combiner circuit that combines the three RF signals from the RF Interconnect Board (40W- 800 MHz PA) or the Combiner Board (70W-800 MHz PA). It then routes the combined RF signal through a single stage circulator and a Low Pass Filter.
Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation DC/Metering Board (QUAD PA Only) The DC/Metering Board in the QUAD Radio serves the same function as it does in other radios. However, its circuitry is modified for compatibility with the QUAD Station. As a result, its logic circuitry is operated at 3.3 VDC.
EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation 900 QUAD PA The Linear Driver Module (LDM) amplifies the low-level RF signal from the Exciter. The LDM consists of a three stage, cascaded, Class AB amplifier, with the final stage in a parallel configuration. See Table 2 for the approximate input and output power of the 900 MHz QUAD LDM. The LDM Output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board.
Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation In the 40W PA, the amplified signals are then combined on the LFM and sent directly to the RF Interconnect Board. In the 70W PA, the amplified signals are then combined on the LFM and sent directly to the Combiner Board. See Table 2 for the approximate total summed output powers of the various LFMs, before output losses.
EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation Following the combiner circuit, the single combined RF signal is then passed through a directional coupler which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a single stage circulator, which protects the PA in the event of high reflected power.
Power Amplifier (PA) EBTS System Manual - Vol 2 PA Theory of Operation temperature is sent from the A/D converter to the BRC. The BRC rolls back forward power if the monitored temperature is excessive.
EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation 1500 MHz Both LFM outputs are input into this module where they are combined, with a branchline coupler, for a single output signal. The RF signal is first coupled to the Exciter module, via the DC/Metering Board, so that it can be monitored. The RF output signal is then passed through a circulator that acts as a protection device for the PA in the event of reflected power.
Power Amplifier (PA) EBTS System Manual - Vol 2 Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is calculated as excessive, forward power is rolled back. If the VSWR calculation is exceedingly out of tolerance, the BRC issues a shut-down command to the Exciter.
