Coaxial Packaged Bi-Directional Amplifiers

Pasternack’s line of bi-directional amplifiers are commonly 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 from Pasternack consist of 2 narrow band models that operate in L-Band (1.35 to 1.39 GHz) and S-Band (2.4 to 2.5 GHz). These designs utilize highly linear Class AB LDMOS semiconductor technology.  A general purpose broadband model is also featured which 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. The key advantage of these designs is fast switching capability (1 μs  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 2.5 dB noise figure and sufficient RF gain levels to maintain a high data rate link.

These 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 company’s bi-directional amplifiers utilize the latest technologies and design methods that offer high power density, efficiency and linearity in small lightweight environmentally sealed packages with SMA connectors. These modules also feature a quick-connect circular locking connector for DC and control functions. All designs use a single voltage supply with voltage regulation.
