Functional Diagram
General Description
The HMC500LP3(E) is
a high dynamic range
10
Vector Modulator RFICs which are targeted for RF
predistortion and feed-forward cancellation circuits,
as well as RF cancellation and beam forming amp-
litude/phase correction circuits. The I & Q ports of
the HMC500LP3(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 150 MHz. With an in-
put 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.
