Noise blanker NB circuit
The input of the NB circuit is extracted from the outputs of second-stage RX mix FETs Q13 and Q14 2SK520 K44 and is applied to the NB hybrid IC1 KCX01 . The input signal is amplified and detected by IC1 then output as a noise blanking signal. The operation of IF amplifier Q15 3SK13KM is stopped by NB switching transistor Q16. Noise components are then eliminated. NB1 is used for short-duration pulses such as ignition noise. NB7 is used for longer-duration, long duration pulse noise such as the...

Circuit Description Udt
The MAT-100 is a high-frequency band automatic antenna tuner that can be remotely controlled. When tuning with a remote controller, the TS terminal of the control cable goes low and a tuning start signal is sent. When the MAT-100 detects that the TS terminal is low, the CPU is reset in order to start tuning. A tuning signal is sent from the remote controller to the sensor circuit of the MAT-100. The sensor circuit detects the frequency count, forward voltage, reflected voltage, impedance, and...

Circuit Description 1
Loop B generates a 37.5-39.5 MHz signal via IC6 CXD1225M with a 1 kHz comparison frequency. The 37.5-39.5 MHz signal is generated by VC06 X59-3440-00 , then divided by 100 in IC7 M54459Lto generate a 10 Hz steps. Fine-frequency adjustment by means of the clarifier is added to loop B under microprocessor control. The 375-395 kHz output signal that was divided by 100 by IC7 is mixed with the 30.3 MHz signal by IC8 SN16913P in order to generate a 30.675-30.695 MHz signal. This frequency passes...

Circuit Description
The TKM-707 PLL is divided into a HET loop and a CAR loop. The HET loop consists of loop A and loop B, and the CAR loop consists of loop C. Figures 2 and 3 show a block diagram of the HET and CAR loops. The following paragraphs describe loops A, B, and C. The reference frequency for loops A, B, and C is 10.1 MHz. This frequency is generated by dividing the 30.3 MHz reference oscillation frequency by 3. Therefore, the frequency accuracy of the HET and CAR is determined by the 30.3 MHz...
