General Description
Features
Functional Diagram
The HMC734LP5(E) is a GaAs InGaP Heterojunc-
tion Bipolar Transistor (HBT) MMIC VCO. The
HMC734LP5(E) integrates a resonator, negative resis-
tance device, varactor diode and features a divide-by-4
frequency output. The VCO’s phase noise perfor-
mance is excellent over temperature, shock, and pro-
cess due to the oscillator’s monolithic structure. Power
output is +18 dBm typical from a +5V supply voltage.
The prescaler function can be disabled to conserve
current if not required. The voltage controlled oscilla-
tor is packaged in a leadless QFN 5x5 mm surface
mount package, and requires no external matching
components.
Dual Output: Fo = 8.6 - 10.2 GHz
Fo/4 = 2.15 - 2.55 GHz
Pout: +18 dBm
Phase Noise: -100 dBc/Hz @ 100 kHz Typ.
No External Resonator Needed
32 Lead 5x5mm SMT Package: 25mm2
Typical Applications
The HMC734LP5(E) is ideal for:
• Point-to-Point/Multi-Point Radio
• Test Equipment & Industrial Controls
• SATCOM
• Military End-Use

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and backside ground 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.
