LA8AKs block diagram.
Lo1UK35 Kriegsmarine VHF tranceiver Frequency range: 41.55-45.75MHz IF = 7.5 MHz. Power: 2.0V - 1.7A, 130V - 50 mA, and -3 V gitter voltage. Measures: H = 468 mm, W = 480 mm, D = 245 mm Weight: 37 kg |
Here is the MF filter frequency filter response. MF frequency is
7.5 MHz.
Vertical span is 100 dB. Horizontal span is 1 MHz.
Here is my special tool for measuring radio frequency
filters. It is important that the measuring equipment not affect the filter. I have designed a balanced high impedance input amplifier with 50 ohm output impedance. A = The amplifier is grounded directly to the chassis. B = AD8130, 270 MHz Differential Receiver Amplifier C = Input capacitor, 1 pF D = SMD 0603 resistors. |
