... IF SAW filter with IF VCO and IF synthesizer blocks. The MAX2395 includes I/Q baseband filters I/Q modulator with VGA, a fully monolithic VCO with PLL, an upconverter mixer VGA, and a power amplifi- er (PA) driver. The use of the quasi-direct modulator scheme ensures 5% (typ) EVM and a 30dB (min) carri- er suppression ...

... The part offers approximately 90dB of gain-control range. An external voltage must be applied using a DAC allowing for dynamic gain control. To minimize the noise contribution from the DAC to the RF signal, place an RC filter at this pin (refer to the MAX2395 Evaluation Kit data sheet). The PA driver is included in the RF VGA. _______________________________________________________________________________________ ...
