W3020 GSM Multiband RF Transceiver

RF Mixer

The W3020 contains two mixers: one for GSM900 band operation and one for GSM1800/1900 band operation.

The RF mixers are double-balanced mixers that can be used in various modes of operation. The ac-grounded

input (pin 56) requires grounding at both the RF and the IF frequencies. If grounding is not placed close to the

device, the RF performance will be compromised. At the output, the mixer is connected to a balanced IF SAW

filter.
