General Description
The HMC500LP3 & HMC500LP3E are high dynamic
range Vector Modulator RFICs which are targeted
for RF predistortion and feed-forward cancellation
circuits, as well as RF cancellation and beam forming
amplitude/phase correction circuits. The I & Q ports
of the HMC500LP3 & HMC500LP3E 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 150 MHz. With an input IP3 of +33 dBm and
input noise floor of -152 dBm/Hz (at -10 dB maximum
gain setting), the input IP3/noise floor ratio is 185 dB.
