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: 25mm
