Functional Diagram
Typical Applications
The HMC786LP4E is Ideal for:
• Cellular/3G & LTE/WiMAX/4G
• Basestations & Repeaters
• GSM, CDMA & OFDM
• Transmitters and Receivers
The HMC786LP4E is a high dynamic range passive
MMIC mixer with integrated LO amplier in a 4x4
SMT QFN package covering 0.7 to 1.1 GHz. Excellent
input IP3 performance of +40 dBm for down conver-
sion is provided for 3G & 4G GSM/CDMA applications
at an LO drive of 0 dBm. With an input 1 dB com-
pression of +25 dBm, the RF port will accept a wide
range of input signal levels. Conversion loss is 7.5
dB typical. Up to 250 MHz IF frequency response
will satisfy GSM/CDMA transmit or receive frequency
plans. The HMC786LP4E is optimized for high side
LO frequency plans for 0.7 - 1.1 GHz RF Band and is
pin for pin compatible with the HMC686LP4E
High Input IP3: +38 dBm
7.5 dB Conversion Loss @ 0 dBm LO
Optimized for High Side LO Input

Pin Number Function Description Interface Schematic
1, 6, 7, 11 - 14,
18, 20, 23 N/C No connection. These pins may be connected to RF
ground. Performance will not be affected.
2, 5, 15, 17 GND These pins and package bottom must be
connected to RF/DC ground.
3RF This pin is matched single-ended to 50 Ohm and DC
shorted to ground through a balun.
4TAP Center tap of secondary side of the internal RF balun.
Short to ground with a zero Ohms close to the package.
8, 10, 24 Vcc1, Vcc2,
Vcc3
Power supply voltage. See application circuit
for required external components.
9LO_BIAS
LO buffer current adjustment pin. Adjust the LO buffer
current through the external resistor R9 shown in the
application circuit (connect 215 Ohms for nominal
operation). This adjustment allows for a trade-off
between power dissipation and linearity performance of
the converter.
16 LO This pin is matched single-ended to 50 Ohm and DC
shorted to ground through a balun.
19 G_BIAS
External bias with a nominal value of 2.5V. See applica-
tion circuit for recommended external components.
G_Bias can be set to between 0 and 5Vdc. This adjust-
ment allows for a trade off between conversion loss
and linearity performance of the converter (see gures
CG, IP3 vs. G_BIAS). The G_bias pin has an internal
15 KOhms resistance to ground and 15 KOhms to Vcc.
Internal resistive divider sets 2.5 V for G_bias and can
be changed externally.
21, 22 IFN, IFP
Differential IF input / output pins matched to differential
50 Ohms. For applications not requiring operation to
DC an off chip DC blocking capacitor should be used.

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 circuit board shown is available from
Hittite upon request.
