W-CDMA LNA/Mixer ICs
IF Output Port
The mixer output appears on the differential IF+ and IF-
pins. These open-collector outputs require an external
inductor to V CC for DC biasing. This port typically
requires a matching network for coupling to an external
IF filter. Figures 1 and 2 show examples of differential
and single-ended IF port connections.
Applications Information
Layout
A properly designed PC board is essential to any
RF/microwave circuit. Keep RF signal lines as short as
possible to minimize losses and radiation. Always use
controlled impedance lines on all high-frequency inputs
and outputs and use low-inductance connections to
ground on all GND pins. At the mixer outputs, keep the
For the best gain and noise performance, use high-
quality components for the LNA input matching circuit,
and solder the slug evenly to the board ground plane.
For the power supplies, a star topology works well to
isolate between different sections of the device. Each
V CC node has its own path to a central V CC . Place
decoupling capacitors that provide low impedance at
the RF frequency of interest close to all V CC connec-
tions. The central V CC should have a large decoupling
capacitor as well. (Use MAX2387/MAX2388/MAX2389
EV kit as an example.)
