User Manual The radio modem consists of three functional entities: 1. Transceiver section – processor, RF transceiver 2. RF section – BALUNs,RF PA, RF filter, RF switch 3. Non-volatile storage – Eeprom Power is supplied to the modem through pins 1 and 2. Pin 1 must be supplied with 3.3 Volts and powers the digital and RF functional entities of the modem. The modem has internal filtering circuitry to smooth out the supply voltage but it has no onboard regulators.
