General Description

Functional Diagram
Electrical Speci cations, TA = +25° C, Vcc = 5V
Typical Applications
The HMC370LP4(E) is ideal for:
• Point-to-Point & VSAT Radios
• Fiber Optic
• Military
The HMC370LP4(E) is an active miniature x4 fre-
quency multiplier utilizing InGaP GaAs HBT
technology in a 4x4 mm leadless surface mount
package. Power output is 0 dBm typical from a
5V supply voltage and varies little vs. input power,
temperature and supply voltage. Suppression of
undesired fundamental and sub-harmonics is >22
dBc typical with respect to output signal level. The
low additive SSB phase noise of -140 dBc/Hz at
100 kHz offset helps the user maintain good sys-
tem noise performance. The HMC370LP4(E) are ideal
for use in LO multiplier chains allowing reduced parts
count vs. traditional approaches.

[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines should have 50 Ohm imped-
ance while the package ground leads and exposed
paddle should be connected directly to the ground
plane similar to that shown. The evaluation circuit
board shown is available from Hittite upon request.
