| HMC508LP5 / 508LP5E v00.0506 MMIC VCO w/ HALF FREQUENCY OUTPUT 7.3 - 8.2 GHz Typical Applications Low noise MMIC VCO w/Half Frequency, for: * VSAT Radio * Point to Point/Multi-Point Radio * Test Equipment & Industrial Controls * Military End-Use Features Dual Output: Fo = 7.3 - 8.2 GHz Fo/2 = 3.65 - 4.1 GHz Pout: +15.0 dBm Phase Noise: -116 dBc/Hz @100 kHz Typ. No External Resonator Needed QFN Leadless SMT Package, 25 mm2 Functional Diagram General Description The HMC508LP5 & HMC508LP5E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC508LP5 & HMC508LP5E integrate resonators, negative resistance devices, varactor diodes and feature a half frequency output. The VCO's phase noise performance is excellent over temperature, shock, and process due to the oscillator's monolithic structure. Power output is +15.0 dBm typical from a +5V supply. The voltage controlled oscillator is packaged in a leadless QFN 5x5 mm surface mount package, and requires no external matching components. 11 VCOS & PLOs - SMT Electrical Specifications, TA = +25 C, Vcc = +5V Parameter Frequency Range Power Output SSB Phase Noise @ 100 kHz Offset, Vtune= +5V @ RFOUT Tune Voltage Supply Current (Icc) (Vcc = +5.0V) Tune Port Leakage Current (Vtune= 13V) Output Return Loss Harmonics/Subharmonics 1/2 2nd 3rd 2 40 20 35 8 10 1.0 Vtune 2 200 240 Fo Fo/2 RFOUT RFOUT/2 +12 +4 -116 13 280 10 Min.

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 circuit board shown is available from Hittite upon request.
