UB9HL-12KFXHIGH POWER AMPLIFIER

Model HL-1.2KFX Explanation on Band Inhibit Circuit (To prohibit 26.028.0 MHz) Drive signal from the transceiver is, at first, received by the (RF) DET UNIT PC1398 and then transferred to PCS1733, FREQ. DETECTOR CIRCUIT. The signal is divided by sixteen (16) through the prescaler IC1, TD7101F. The resulting signal is sent to the IC2, PIC micro processor, where the signal frequency is counted If the drive signal is judged to fall in the band width of 26.0 to 28.0 MHz, IC2 issues the command to open the relay RL1, of which contacts are in series with the STAND-BY (STBY/OPER.) control circuit, as is shown around T/R pin of PC1698, CONT’L UNIT and STBY, RCA-Jack located at the rear panel of the amp. Once the STAND-BY control circuit becomes open, the amp keeps stand-by mode and amplifier gain is nil, even if it is driven by such signals between 26.0 and 28.0 MHz.

Model HL-1.2KFX-Theory of Operation(How It Works/ RF Signal Flow)- 1/2 Model HL-1.2KFX Theory of Operation (How It Works/ RF Signal Flow) When the amplifier is in a stand-by (STBY) mode, gate bias(voltage) to the final FET’s are cut off. Also input(TX) relay and output(ANT) relay are free(open) from the amplifier. Therefore the signals from the transceiver and/or from the antenna will all by-pass the amplifier. (By-Pass/ Stand-By Mode) When the amplifier is in an OPER.(operate) mode and keyed by the transceiver, forward gate bias is applied to the final power FET’s and at the same time input and output relays are closed to the IN and OUT of the amplifier. Consequently the amplifier is ready to work with the designed amplification gain. RF Drive signal from the transceiver reaches RF IN of DET(Detector) Unit, PC1398, where input power level is measured. If the in drive power is over 100W, the protection circuit will issue a command of “Over-Drive”, to shut down the amplifier. DET UNIT also measures the amplified output level of the amplifier. When the ratio of output and input(drive) powers is much lower than the designed value, CONT UNIT(PC1698) will judge that final amplifier is out of order and/or that output LPF (low pass filter) is band miss-set. Drive signal having passed INPUT DET part will be lead to PC1733, Freq. DET UNIT, where the frequency of the drive signal is counted by IC. If the frequency is between 26.0 and 28.0 MHz, CONT(ROL) UNIT issues the command to shut down the amplifier, according to FCC rule. Then drive signal reaches the input of PA UNIT, PC1662. Signal is attenuated by 3 dB attenuator before entering the gates of FET’s. Four FET’s (SD2933’s) form a broad-band parallel push-pull linear amp with a gain of approx. nine times. Model HL-1.2KFX-Theory of Operation(How It Works/ RF Signal Flow)- 2/2 Next, the amplified signal will pass through LPF(low pass filter) UNIT, PC1399, where the harmonics are filtered and removed. Filtered output signal will then go through the OUT DET(output power detector) of DET UNIT, PC1398 to reach RF OUT, J2(ANT) terminal. OUT DET measures the output power level of the signal. This power level is shown on the analog multi-meter, PF scale(forward power).
