The IC is ideal for use in the transmitter modulation loop by providing extremely small form factor and low phase noise.
The IC has two VCOs, one for GSM and a second for DCS/PCS.
The IC has two separate buffer amplifiers to drive an external high power amplifier, one for GSM900 band and the other one for DCS1800/ PCS1900 bands.
The IC also has a differential buffer amplifier to drive a mixer for the offse...
