General Description
Functional Diagram
10
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.
