Typical Applications Phase-Locked Oscillator for: SAT Radio Point-to-Point & Point-to-Multi-Point Radio Test Equipment & Industrial Controls Military End-Use Functional Diagram Features Pout: +9 dbm Phase Noise: -11 dbc/hz @1 KHz Typ. Single Supply: +5 @ 34 ma + @ 28 ma 24 Lead 4x4mm QFN Package: 9 mm 2 General Description 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 +5 supply voltage. All functions (CO, Op-Amp, PFD, Prescaler) are fully integrated while providing allowances for off-chip customer specifi c loop components. The PLO MMIC accepts a single-ended or a differential reference oscillator input signal in the range of 23 to 24 MHz, and a digital Lock Detector (LD) output is provided to confi rm the status of the loop. The phase-locked oscillator is packaged in a leadless QFN 4 x 4 mm surface mount package.

Application Circuit - 169
Evaluation PCB The circuit board used in the fi nal application should use RF circuit design techniques. Signal lines should have 5 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. - 17
