Description

The AD6459 is a 3 V, low power receiver IF subsystem for operation at input frequencies as high as 500 MHz and IFs from 5 MHz up to 50 MHz. It is optimized for operation in GSM, DCS1800 and PCS1900 receivers. It consists of a mixer, an IF amplifier, I and Q demodulators, a phase-locked quadrature oscillator, a precise AGC subsystem, and a biasing system with external power-down.

The AD6459's low noise, high intercept mixer is a doublybalanced Gilbert-Cell type. It has a nominal 11 dBm inputreferred 1 dB compression point and a 0 dBm input-referred third-order intercept. The mixer section of the AD6459 also includes a local oscillator (LO) preamplifier, which lowers the required LO drive to 16 dBm.
