Pasternack unveils coaxial packaged bi-directional RF amplifiers operating up to 3GHz

Pasternack Enterprises Inc of Irvine, CA, USA (which makes both passive and active RF, microwave and millimeter-wave products) has introduced a line of bi-directional amplifiers that are used for sending and receiving radio signals in key applications such as unmanned aerial vehicles (UAV), unmanned ground vehicles, L- and S-band radar, military radio, commercial air-traffic control, weather and earth observation, satellites and high-gain driver power amplifiers.

The new bi-directional RF amplifiers consist of two narrow-band models that operate in the L-band (1.35-1.39GHz) and S-band (2.4-2.5GHz), using highly linear Class AB LDMOS semiconductor technology. In addition, a general-purpose broadband model covers the 30MHz to 3GHz frequency range, using Class A gallium arsenide (GaAs) technology. Typical gain levels range from 20dB to 23dB with ±0.5dB gain flatness. The key advantage of the designs is fast switching capability (1μs typical) between transmit (Tx) and receive (Rx) states where high output power is generated, while at the same time the sensitive receiver section has a 2.5dB noise figure and sufficient RF gain levels to maintain a high-data-rate link.

The new models are designed for use in both military and commercial applications and are capable of supporting any signal type and modulation format, including but not limited to 3-4G telecom, WLAN, OFDM, DVB and CW/AM/FM. The firm says that its bi-directional amplifiers use the latest technologies and design methods, offering high power density, efficiency and linearity in small lightweight environmentally sealed packages with SMA connectors. The modules also feature a quick-connect circular locking connector for DC and control functions. All designs use a single voltage supply with voltage regulation.   

"Pasternack's selection of in-stock bi-directional amplifiers exhibit fast transmit and receive switching capabilities, long transmission range and highly efficient operation, which are critical for use in applications such as unmanned aerial vehicles and cellular networks," says Tim Galla, Active RF Components product manager.

Pasternack's broadband bi-directional amplifiers are in-stock and ready to ship.
