GaAs HBT VECTOR

MODULATOR 1.8 - 2.7 GHz

v00.1007

General Description

Features

Functional Diagram

The HMC631LP3 & HMC631LP3E are high dynamic

range Vector Modulator RFICs which are targeted

for RF predistortion and feed-forward cancellation

circuits, as well as RF cancellation, beam forming and

amplitude/phase correction circuits. The I & Q ports

of the HMC631LP3(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 200 MHz. With an

output IP3 of +26 dBm and output noise floor of -160

dBm/Hz (at maximum gain setting), the IP3/noise floor

ratio is 186 dB.

Continuous Phase Control: 360°

Continuous Gain Control: 40 dB

Output Noise Floor: -160 dBm/Hz

Input IP3: +35 dBm

Typical Applications

The HMC631LP3(E) is ideal for:

• Cellular/3G & WiMAX Systems

• Wireless Infrastructure HPA &

MCPA Error Correction

• Pre-Distortion or Feed-Forward Linearization

• Beam Forming & Nulling Circuits
