GaAs HBT VECTOR

MODULATOR 700 - 1000 MHz

v00.1007

General Description

Features

Functional Diagram

The HMC630LP3 & HMC630LP3E are high dynamic

range Vector Modulator RFICs which are targeted

for RF predistortion and feed-forward cancellation

circuits, as well as RF beam forming and amplitude/

phase correction circuits. The I & Q ports of the

HMC630LP3(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 180 MHz. With an out-

put IP3 of +24.5 dBm and output noise floor of -162

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

noise floor ratio is 186.5 dB.

Continuous Phase Control: 360°

Continuous Gain Control: 40 dB

Low Output Noise Floor: -162 dBm/Hz

High Input IP3: +34 dBm

Typical Applications

The HMC630LP3(E) is ideal for:

• Wireless Infrastructure HPA &

MCPA Error Correction

• Pre-Distortion or Feed-Forward Linearization

• Cellular / 3G Systems

• Beam Forming or RF Cancellation Circuits
