Broadband

Coaxial Packaged Bi-Directional Amplifiers Yield Fast Switching

19 August 2015

A new line of bi-directional amplifiers from Pasternack are designed 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 RF amplifiers consist of two narrow band models that operate in L-Band (1.35 to 1.39 GHz) and S-Band (2.4 to 2.5 GHz). The designs use highly linear Class AB LDMOS semiconductor technology. A general-purpose broadband model is also featured that covers 30 MHz to 3 GHz and uses Class A GaAs semiconductors. Typical gain levels for these amplifiers range from 20 to 23 dB with ±0.5 dB gain flatness.

A key advantage of the amplifier designs is fast switching capability (1 microsecond typical) between Transmit (Tx) and Receive (Rx) states, where high output power is generated. At the same time, the sensitive receiver section has a 2.5 dB noise figure and sufficient RF gain levels to maintain a high data rate link.

These models target 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 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 broadband bi-directional amplifiers are in-stock and ready to ship.
