HMC500LP3 / 500LP3E
General Description
Features
Functional Diagram
The HMC500LP3(E) is a 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 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 oor of -152 dBm/
Hz (at -10 dB maximum gain setting), the input IP3/
noise oor ratio is 185 dB.

Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase () setting, the
voltages applied to these ports in all measurements are calculated as follows:
Where Vmi and Vmq are the I and Q voltage settings corresponding to maximum isolation at room temperature and F = 2 GHz.
Note that G=10X and Gmax = 10Y where x = and y = . Nominally Vmi = Vmq = 1.5V, Gmax = 0.316.

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
