Cryogenic Low Noise Amplifier
The model APTC4-00101800-1910-D4 is a cryogenic low noise amplifier (LNA) designed to operate at extremely low temperatures (below the liquid helium temperature of 16 K) in order to take advantage of the decreased noise figures at these levels. This model is an ultrawideband LNA that operates in a frequency range from 0.1 to 18 GHz. These amplifiers offer low DC power options (as low as +3 VDC), low current consumption and a lightweight, compact housing/design.

MMIC Voltage-controlled Oscillator
The model HMC586LC4B is an SMT wideband GaAs InGaP HBT MMIC VCO that incorporates the resonator, negative resistance device and varactor diode. This fully integrated MMIC VCO offers a wide output frequency tuning range of 4 to 8 GHz, with +5 dBm output power and low SSB phase noise of –100 dBc/Hz at 100 kHz offset. Output power and phase noise performance are excellent over temperature due to the oscillator’s monolithic construction.
