HMC510LP5 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO from Hittite Microwave Corporation. The frequency range is 8.45-9.55 GHz. The VCO integrates resonators, negative resistance devices, varactor diodes, and features half frequency and divide-by-4 outputs. The VCO's phase noise performance is excellent over temperature, shock, and process due to the oscillator's monolithic structure. Power output is +13 dBm typical from a +5V supply voltage. The prescaler and RF/2 functions can be disabled to conserve current if not required. The voltage controlled oscillator is packaged in a leadless QFN 5x5 mm surface mount package, and requires no external matching components.

The HMC305LP4 and HMC305LP4E are broadband 5-bit positive control GaAs IC digital attenuators with CMOS compatible serial-to-parallel drivers packaged in leadless QFN 4x4 mm SMT packages. Covering 0.7 to 3.8 GHz, the insertion loss is typically less than 1.5 to 2 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3V to +5V applied through an external 5k Ohm resistor is required. The HMC305LP4 / HMC305LP4E is ideal for: • Cellular/3G Infrastructure • Fixed Wireless, WiMax & WiBro • Test Instrumentation
