Functional Diagram

General Description

The HMC391LP4 & HMC391LP4E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs

with integrated resonators, negative resistance

devices, varactor diodes, and buffer ampliﬁers.

Covering 3.9 to 4.45 GHz, the VCO’s phase noise

performance is excellent over temperature, shock,

vibration and process due to the oscillator’s monolithic

structure. Power output is 5.0 dBm typical from a

single supply of +3V @ 30 mA. The voltage controlled

oscillator is packaged in a low cost leadless QFN 4 x 4

mm surface mount package.

Evaluation PCB

List of Materials for Evaluation PCB 105706 ^[1]

The circuit board used in the ﬁnal application should

use RF circuit design techniques. Signal lines

should have 50 ohm impedance while the package

ground leads and exposed 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.
