CA32

RF Amplifiers Overview

The CA32 is a discrete hybrid RF amplifier designed for broadband operation from 100 MHz to 2 GHz. Utilizing thin film manufacturing processes, this single-stage GaAs FET feedback amplifier ensures accurate performance and high reliability. The device features a low noise figure of 3.5 dB typical, high third-order intercept point of +32 dBm typical, and high output level of +21 dBm typical. It maintains low VSWR of 1.8:1 typical. An internal RF choke provides DC power supply decoupling. Both TO-8 and surface mount packages are hermetically sealed, with MIL-STD-883 environmental screening available.

RF Amplifiers Feature Summary

• Discrete hybrid design using thin film manufacturing for high reliability
• Single-stage GaAs FET feedback architecture
• Hermetically sealed TO-8 and surface mount packages

RF Amplifiers Applications

• Broadband RF signal amplification
• High-reliability communication systems
• Military and aerospace applications requiring MIL-STD-883 screening

RF Amplifiers Procurement Notes

Verify the specific package variant (TO-8 or surface mount) required for your application, as both are available. Confirm if MIL-STD-883 environmental screening is necessary, as it is an optional feature. Ensure compatibility with the 50-ohm system impedance specified in the electrical characteristics. Check RoHS compliance status, particularly if ordering connectorized versions which may have different regulatory standings.

RF Amplifiers Selection Notes

Select the CA32 when a cascadable amplifier is needed within the 100 MHz to 2 GHz range. Its low noise figure and high linearity make it suitable for sensitive receiver front-ends. Consider the hermetic sealing for harsh environments. Compare against similar models like A32 or CA32-1 if specific gain or frequency adjustments are required. The thin film technology offers stability over temperature variations compared to standard monolithic designs.
