HMC631LP3 / 631LP3E
General Description
Features
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 oor of -160
dBm/Hz (at maximum gain setting), the IP3/noise oor
ratio is 186 dB.
Continuous Phase Control: 360°
Continuous Gain Control: 40 dB
Output Noise Floor: -160 dBm/Hz
Input IP3: +35 dBm
16 Lead 3x3mm SMT Package: 9mm2
Typical Applications
The HMC631LP3(E) is ideal for:
• Cellular/3G & WiMAX Systems
• Wireless Infrastructure HPA &
MCPA Error Correction
• Pre-Distortion or Feed-Forward Linearization
• Beam Forming & Nulling Circuits

Pin Description
Pin Number Function Description Interface Schematic
1, 4, 10 - 12 N/C No connection. These pins may be connected to RF ground.
Performance will not be affected
2, 3 IN, IN Differential RF inputs, 100 Ohms differential impedance. (i.e.
each pin is 50 Ohms to ground). Must be DC blocked.
5, 15 I In-phase control input. Pins 5 and 15 are redundant.
Either input can be used.
6, 16 Q Quadrature control input. Pins 6 and 16 are redundant.
Either input can be used.
7, 8, 13, 14 Vcc
Supply Voltage, pins are DC connected on-chip. It is only nec-
essary to supply Vcc to any 1 of the 4 pins, but all 4 pins must
be bypassed to ground. (See application circuit).
9 RFOUT RF Output: Must be DC blocked.
GND Ground: Backside of package has exposed metal ground
paddle which must be connected to RF/DC ground.

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:
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.
