GaAs HBT VECTOR

MODULATOR 1.8 - 2.2 GHz

v02.1109

General Description

Features

Functional Diagram

The

HMC500LP3(E)

is

a

high

dynamic

range

Vector Modulator RFICs which are targeted for RF

predistortion and feed-forward cancellation circuits,

as well as RF cancellation and beam forming amp-

litude/phase correction circuits. The I & Q ports of

the HMC500LP3(E) can be used to continuously vary

the phase and amplitude of RF signals by up to 360

degrees and 40 dB respectively, while supporting a

3 dB modulation bandwidth of 150 MHz. With an in-

put IP3 of +33 dBm and input noise floor of -152 dBm/

Hz (at -10 dB maximum gain setting), the input IP3/

noise floor ratio is 185 dB.

Typical Applications

The HMC500LP3(E) is ideal for:

• Wireless Infrastructure HPA &

MCPA Error Correction

• Pre-Distortion or Feed-Forward Linearization

• PCS, GSM and W-CDMA Systems

• Beam Forming or RF Cancellation Circuits
