Pasternack Introduces Input Protected Low-Noise Amplifiers from 10 MHz to 3.5 GHz

Pasternack Input Protected LNAPasternack, a leading provider of RF, microwave and millimeter wave products, has released a new line of input-protected low-noise amplifiers (LNA's) that can handle up to +30 dBm CW input power without any damage. These input-protected low-noise amplifiers (LNA's) are ideal for radar systems, EW applications, military/microwave radios, wireless and satellite communications, and test instrumentation.

The new line of input-protected low-noise amplifiers consists of 12 different models that cover a broad range of frequency bands from 10 MHz to 3.5 GHz. These amplifiers exhibit typical performance that includes low noise figure levels from 0.8 to 1.6 dB, high-small signal gain ranging from 25 to 40 dB, and low VSWR levels from 1.3:1 to 1.5:1. This performance is achieved through the use of hybrid MIC designs that incorporate PIN diode limiter circuitry and Enhancement mode (Emode) GaAs pHEMT semiconductor devices. These amplifiers operate with a bias voltage of +12V typical over the temperature range of -40°C to +85°C. The 50 Ohm, SMA connectorized modules are unconditionally stable, include built-in voltage regulation and have DC blocking capacitors on the RF ports.

The robust performance of these LNA's is required to maintain receiver sensitivity over a wide range of RF input signal levels for applications that may involve radar systems, test instrumentation and wireless, and satellite communications.
