User Manual
Radioddity LPFX7 Low Pass Filter is mainly used to suppress transmitter
harmonics during transmission and reception.
Introduction
1. When using with the PAX100, 100% suppression effect can be achieved.
using with other radios or devices, 80-95% suppression effect can be
2. When
achieved.
3. Working Voltage: 13.8V | Working Current: 0.1-0.5A
4. Maximum Input Power: 100W for CW, 200W for SSB. If the maximum range is
exceeded, there will be an overload, which may damage the filter.
5. Frequency Range Support：10M、15M、20M、40M、80M
6. Harmonic suppression：
10M & 15M, 20M, and 40M＞30db
80M＞51db
Operation Guide
1. Connect the G90 to the PAX100 then to the LPFX7 and finally to an antenna.
2. Prepare the DC power supply: set the DC voltage to 13.8V output and the maximum
current to 20A.
Note: The power cord of LPFX7 can be directly connected to the power cord of G90. Pay
attention to the positive and negative poles.
3. Power on in the following order
Turn on the DC power supply then turn on G90 (the PAX100 will automatically power up)
then turn on LPFX7
4. Power and frequency setting
① Set the output power of G90 from 2 to 10 watts
② Set the G90 to the desired frequency
③ Select the working band of LPFX7 according to the G90 frequency.
Note: It will damage the LPFX7 if the transmitting frequency/band of the radio and the
