GaAs HBT VECTOR
MODULATOR 1.8 - 2.7 GHz
v00.1007
HMC631LP3 / 631LP3E
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 oor of -160
dBm/Hz (at maximum gain setting), the IP3/noise oor
ratio is 186 dB.
Continuous Phase Control: 360°
Continuous Gain Control: 40 dB
Output Noise Floor: -160 dBm/Hz
Input IP3: +35 dBm
16 Lead 3x3mm SMT Package: 9mm

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
