HMC631LP3 / 631LP3E
GaAs HBT VECTOR
MODULATOR 1.8 - 2.7 GHz
Features

16 Lead 3x3mm SMT Package: 9mm2
General Description
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.

IN, IN
Differential RF inputs, 100 Ohms differential impedance. (i.e.
each pin is 50 Ohms to ground). Must be DC blocked.
I
In-phase control input. Pins 5 and 15 are redundant.
Either input can be used.
6, 16
7, 8, 13, 14
Quadrature control input. Pins 6 and 16 are redundant.
Q Either input can be used.
Supply Voltage, pins are DC connected on-chip. It is only nec-
Vcc essary to supply Vcc to any 1 of the 4 pins, but all 4 pins must
be bypassed to ground. (See application circuit).
