General Description
The HMC622LP4E is a highly integrated converter
IC that operates from 1.8 to 3.9 GHz for both up-
conversion and downconversion applications. The
HMC622LP4E incorporates a high dynamic range,
double-balanced mixer core with integrated LO and
IF amplifiers, making it ideal for compact transceiver
applications in GSM, WCDMA, TD-SCDMA, WiBro
and WiMAX. This versatile converter RFIC operates
with a low LO input power level of only +3 dBm, pro-
vides up to 10 dB conversion gain, and exhibits +23
dBm Input IP3 in downconversion mode. This RFIC
provides up to 12 dB conversion gain in upconverter
mode. Specific evaluation boards are available for
both upconversion and downconversion modes.
Electrical Specifications, TA = +25° C, LO = +3 dBm, VddIF = BIAS = +5V*
