Continuously Variable Coaxial Attenuators
RLC Electronics’ continuously variable coaxial attenuators offer wide bandwidths up to 40 GHz for microwave applications where continuous adjustment of signal level is required with low insertion loss and good impedance matching. Unique mechanical packaging with a locking, non-translating shaft allows a compact assembly. The construction of the transmission line and shaped, proprietary lossy material give flat response over a wide range of attenuation. Units are available with locking screwdriver, panel mount or dial knob adjustment options.

AMPLIFIERS
GaN Solid-State Power Amplifier
Aethercomm model number SSPA 0.020-1.000-350 is a high-power, multi-decade bandwidth, GaN solid-state power amplifier. It is packaged in an enclosure that is optimized for airborne or ground applications that require survival in high performance shock and vibration environments. Nominal linear output power is 100 to 200 W but power levels at saturation of 300 to 400 W are typical from 100 to 900 MHz.

Efficient, High-Power 20 to 55 GHz Amplifier
The AMM-6702 is a gamechanger. Featuring an ultra-wide 20 to 55 GHz bandwidth, over 25 dB gain and up to +23 dBm saturated output power with only a 0 dBm input, this GaAs MMIC amplifier consumes a mere 570 mW. High linearity broadband mmWave mixers such as the company’s MM1-1850S require high-power broadband LO driver amplifiers, but these amps were largely absent from the market at frequencies above 40 GHz—until now.
