RF9986
8 PCS LOW NOISE AMPLIFIER/MIXER
Typical Applications
• CDMA/TDMA/DCS1900 PCS Systems
• PHS 1500/WLAN 2400 Systems
• General Purpose Down Converter
• Micro-Cell PCS Base Stations
• Portable Battery-Powered Equipment
Product Description
The RF9986 is a monolithic integrated receiver front-end
for PCS, PHS, and WLAN applications. The IC contains
all of the required components to implement the RF func-
tions of the receiver front-end except for the passive filter-
ing and LO generation. It contains an LNA (low-noise
amplifiers), a double-balanced Gilbert cell mixer, a bal-
anced IF output, an LO isolation buffer amplifier, and an
LO output buffer amplifier for providing the buffered LO
signal as an output. The IC is designed to operate from a
single 3.6V power supply.

Notes:
1. C11 is selected to fine tune L4 for IF output match at 210 MHz.
2. R3 is not normally populated. For applications requiring additional LNA IP3, see the datasheet for
recommended resistance values.
3. C2 and C3 are not normally populated. If C2 and C3 are populated, the LNA and mixer can be tested
independently; in this case, C1 and C5 should be removed.
