The receiver provides a low noise down-conversion from RF to a 200 - 600 MHz intermediate frequency. 40 dB of gain control is available prior to the down-conversion for optimization of noise and linearity. The gain control is divided between the variable gain LNA and a 3 bit digital attenuator with 4 dB step size. An off-chip filter between the LNA and mixer can be used for image rejection. The IF output has an off-chip matching network for flexible frequency planning and SAW filter selection. The transmitter up-converts to RF from a 200 - 600 MHz IF. The up-conversion mixer output is brought off chip to allow image band and LO suppression prior to final amplification. The transmit attenuator has a three bit digital interface with 4 dB resolution and a total range of 25 dB.
