HIGH IP3 GaAs MMIC
MIXER, 450 - 500 MHz
v02.0705
General Description
Features
Functional Diagram
Input IP3: +32 dBm
Conversion Loss: 9.5 dB
Low External Part Count
Ultra Small MSOP8 Package: 14.8 mm2
Included in the HMC-DK003 Designer’s Kit
Electrical Speci cations, TA = +25°C, LO = +17 dBm, IF = 70 MHz [1]
Typical Applications
High Dynamic Range Infrastructure:
• GSM 450 & GSM 480
• CDMA 450
• Private Land Mobile Radio
The HMC387MS8 & HMC387MS8E are high dynamic
range passive MMIC mixers in plastic surface mount
8 lead Mini Small Outline Packages (MSOP) covering
450 to 500 MHz. Excellent input IP3 performance
of +32 dBm for down conversion and +29 dBm for
up conversion is provided for both GSM/CDMA
based cellular and Private Land Mobile Radio
applications at an LO drive of +17 dBm. The mixer
also has excellent performance with as little as
+13 dBm LO drive yielding a +30 dBm input IP3.
With a 1 dB compression of +22 dBm, the RF port
will accept a wide range of input signal levels.
Conversion loss is 9.5 dB typical. The DC to 150
MHz IF frequency response will satisfy many cel-
lular transmit or receive frequency plans. The
HMC387MS8(E) input IP3 performance coupled with
its high P1dB rivals traditional active FET mixers while
offering a much smaller 14.8mm2 standard IC footprint
and no DC bias.

Pin Descriptions
Pin Number Function Description Interface Schematic
1LO
This pin is AC coupled & matched to 50 Ohms
when an external series inductor (L1) and shunt
capacitor (C1) is connected to the LO. Choose values
of L1 and C1 to optimize LO frequency response.
See Application Circuit herein.
2, 4 N/C Not connected.
3, 6, 7 GND This pin must be connected to RF ground.
5IF
This pin is DC coupled. For applications not requiring
operation to DC this port should be DC blocked
externally using a series capacitor.
Choose value of C1 to pass IF frequency desired.
For operation to DC, this pin must not sink/source
more than 40 mA of current or failure may result.
8RF This pin is DC coupled & matched to 50 Ohms
from 450 - 500 MHz

[3] Unless otherwise noted, all measurements performed as a
downconverter with low side LO & IF = 200 MHz
[4] LO Frequency optimized. See application circuit herein.
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 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 circuit board
shown is available from Hittite upon request.
