General Description
Functional Diagram
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.

Application Circuit
* Pins 15 & 16 are redundant I & Q inputs.
Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase (θ) setting, the
voltages applied to these ports in all measurements are calculated as follows:
MODULATORS - SMT
10
G
Cos (θ )
G max
G
Q (G,θ ) = Vmq + 1.0V
Sin (θ )
G max
I (G,θ ) = Vmi + 1.0V
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 =
Gain Setting ( dB)
and

y = Max

Nominally Vmi = Vmq = 1.5V, Gmax = 0.316.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected 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.
