LO MON Frequency Calculation
Calculate the LO MON frequency as follows.
1. First, find the difference between the TX Frequency and the Multiplier
Frequency.
2. Then subtract 140 MHz from the difference to arrive at the LO MON
frequency.
The LO MON frequency is always between 2060 and
2160 MHz.
022 10300 8000 < 8100
023 10400 8100 < 8200
024 10500 8200 < 8300
025 10600 8300 < 8400
026 10700 8400 < 8500

Multiplier Frequency = 9800.000 MHz Transmit Frequency = 11192.500 MHz
Transmit Frequency = 7561.500 MHz
Multiplier Frequency = 8900.000 MHz
Difference = 2238.500 MHz Difference = 2292.500 MHz
