RFIC DOWNCONVERTER SMT, 1.8 - 2.7 GHz

v01.0708

General Description

Features

Functional Diagram

the

Hmc623LP4e

is

a

highly

integrated

downconverter ic that operates from 1.8 to 2.7 GHz.

the Hmc623LP4e incorporates a high dynamic

range, single-balanced mixer core with integrated

rF, 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 0 dBm, provides up to 33 dB

conversion gain, and exhibits +39 dBm output iP3.

the integrated rF amplifier provides for an overall

noise figure of only 4 dB.

Low noise Figure: 4 dB

High output iP3: +39 dBm

Low input Lo Drive: 0 dBm

High Lo to rF isolation: 45 dB

High conversion Gain: 33 dB
