Description
Amplifiers, filters, combiners and other material for high power AM transmitters
To increase power or performance of your AM transmitter you may need one of these accessories.
MW/SW SWR/PWR detector board
This board is used to measure forward and reflected power of your MW or SW transmitter. Diode detectors are used. Frequency response is not flat, output voltage is lower at low frequencies.
Technical specifications:
– Power: 2500W Max
– Frequency band: 1.5-54MHz
– Board size: 65x50mm
7-POLE CHEBYSHEV LOW PASS FILTER
This board is used to filter out harmonics of transmitted signal. Two or three of these can be used, if desired, to reduce harmonics even more. Filter is offered in three variants with cutoffs at 1800KHz, 1000KHz or 750KHz.
Technical specifications:
Type: 7-pole Chebyshew
Cutoff frequency: 1800KHz, 1000KHz or 750KHz
Max peak power: 2000W
Input and output impedance: 50Ohm unbalanced
Board size: 40mm x 100mm
