CA55

RF Amplifiers Overview

The CA55 is a discrete hybrid RF amplifier manufactured by MACOM Technology Solutions using thin film processes. It operates within a frequency range of 10 MHz to 500 MHz. The device features a single-stage bipolar transistor feedback design optimized for broadband performance and high reliability. Typical electrical specifications include a medium output level of +11 dBm and a third-order intercept point (IP3) of +24 dBm. Both TO-8 and surface mount package options are available, with hermetic sealing capabilities.

RF Amplifiers Feature Summary

• Discrete hybrid design utilizing thin film manufacturing processes for accurate performance
• Single-stage bipolar transistor feedback architecture
• Hermetically sealed construction in both TO-8 and surface mount packages

RF Amplifiers Applications

• Broadband RF signal amplification
• High reliability electronic systems
• Military equipment applications

RF Amplifiers Procurement Notes

Verify the specific package variant required, as the CA55 is available in both TO-8 and surface mount configurations. Confirm environmental screening requirements against MIL-STD-883 standards if applicable to the target application. Ensure compatibility with the intended frequency range of 10 MHz to 500 MHz before finalizing component selection.

RF Amplifiers Selection Notes

Select the CA55 when a cascadable amplifier with medium output power is required. The choice between TO-8 and surface mount packages depends on the mechanical constraints of the assembly. Consider the typical +11 dBm output and +24 dBm IP3 values to ensure they meet system linearity and gain requirements within the specified 10 MHz to 500 MHz operational band.

RF Amplifiers Part Context

The CA55 belongs to a family of cascadable amplifiers from MACOM, which includes related models such as the A57 and A53. These components share similar design philosophies focusing on hybrid thin-film technology and robust performance across wide bandwidths. The CA55 specifically targets applications requiring reliable amplification in the VHF/UHF spectrum ranges.

RF Amplifiers Replacement Considerations

The A57 and A53 are documented as similar cascadable amplifiers covering the 10 to 500 MHz range. Verify pinout compatibility and specific electrical tolerances when substituting these models.
