HMC535LP4 / 535LP4E
PHASE-LOCKED OSCILLATOR,
14.7 - 15.4 GHz
v01.1009
General Description
Features
Functional Diagram
The HMC535LP4 & HMC535LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC PLOs.
The PLO’s phase noise performance is excellent
over temperature, shock, and process due to the
oscillator’s monolithic structure. Power output is
+9 dBm typical from a +5V supply voltage. All fun-
ctions (VCO, Op-Amp, PFD, Prescaler) are fully
integrated while providing allowances for off-chip
customer speci c loop components. The PLO MMIC
accepts a single-ended or a differential reference
oscillator input signal in the range of 230 to 240 MHz,
and a digital Lock Detector (LD) output is provided
to con rm the status of the loop. The phase-locked
oscillator is packaged in a leadless QFN 4 x 4 mm
surface mount package.
Pout: +9 dBm
Phase Noise: -110 dBc/Hz @100 KHz Typ.
Single Supply: +5V @ 340 mA
+12V @ 28 mA
24 Lead 4x4mm QFN Package: 9 mm
Typical Applications
Phase-Locked Oscillator for:
• VSAT Radio
• Point-to-Point & Point-to-Multi-Point Radio
• Test Equipment & Industrial Controls
• Military End-Use

Evaluation PCB
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 backside ground paddle 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 board should be mounted to an appropriate heat sink. The evaluation
circuit board shown is available from Hittite upon request.
