Amplifiers and Oscillators

Mini-Circuits ZHL-16W-43+ offers high power (16W) with rugged reliability over a broad frequency range from 1800 to 4000 MHz. This model includes temperature sensing circuits for automatic shutdown and output load protection to operate into a short or an open making it ideal for use in laboratory or field applications.

M/A-COM Technology Solutions amplifiers are used extensively in RF, microwave and mmWave commercial, military and space applications.

Mini-Circuits PMA-545+ is a E-PHEMT based Ultra-Low Noise MMIC Amplifier operating from 100 MHz to 6 GHz with a unique combination of low noise and high IP3 making this amplifier ideal for sensitive receiver applications. This design operates on a single 3V supply and is internally matched to 50 Ohms.

Small Signal Gain 35dB min. 20 W Typical. P3dB.
