Solid-state Linear RF Power Amplifier
The model GRF2034NL RF power amplifier designed for linear applications in the PCS frequency range utilizes linear power devices that provide good linearity, high gain and wide dynamic range. High efficiency operation is achieved by employing unique microstrip networks and advanced GaAs FET devices. Designed for high reliability, the power amplifier features a built-in, voltage-regulated bias supply and electromagnetic and RF interference filters.
Ophir RF, Los Angeles, CA (310) 306-5556.
The QGU series ultrabroadband pHEMT-based general-purpose amplifiers offer nominal gains of 20 and 40 dB with nominal output power of 17 dBm across the entire K- and Ka- frequency bands. Each amplifier has internal bias circuitry that generates gate control voltages and provides proper voltage sequencing and reverse/over-voltage protection from a single external bias of 8 to 12 V DC. The amplifiers are well suited for very wide bandwidth power amplification. K-female connector input/output ports are included, but standard rectangular waveguide (K- and Ka-band) and double-ridge waveguide (18 to 40 GHz) connectors also are available.

High Density Forward Path Amplifier
The RF Worx™ forward path amplifier is designed to optimize space utilization and enhance system flexibility in high density broadband networks. The amplifier can be housed in an RF Worx chassis that combines active and passive components or can operate as a stand-alone active platform. In addition to standard 100/110 and 220/240 V AC power, the amplifier offers an optional -48 V DC power supply that meets the specifications required for telephony deployment. Other features include digitally variable gain and slope control, low noise, good distortion characteristics, and flat frequency response.
