HMC595

RF Switches Overview

The HMC595 is a GaAs MMIC SPDT transmit/receive switch operating from DC to 3 GHz with a 50 Ohm impedance. It features low insertion loss of 0.5 dB and high isolation of 18 dB at 3 GHz. The device supports a P1dB compression point of 39 dBm and an IIP3 of 63 dBm, ensuring minimal distortion in high-power applications. Powered by a 5V supply, it is housed in a compact SOT-23-6 surface-mount package. Designed for robust performance, it operates within a temperature range of -40°C to +85°C.

RF Switches Feature Summary

• Provides single-pole double-throw switching capability for RF signal routing
• Engineered for very low distortion performance in high power levels
• Supports control of signals ranging from DC up to 3 GHz frequency

RF Switches Applications

• Transmit/receive switching in cellular base stations

RF Switches Procurement Notes

Verify component status carefully as the HMC595 is listed as obsolete by Analog Devices Inc. and may no longer be manufactured. Confirm availability through authorized distributors or surplus suppliers if sourcing is required. Ensure that any replacement components meet the same electrical specifications and pinout compatibility. Check RoHS compliance and packaging details against specific project requirements before finalizing procurement decisions.

RF Switches Selection Notes

Select this component for applications requiring low distortion and high linearity in RF switching roles. The wide frequency range up to 3 GHz makes it suitable for various wireless standards. Consider the SOT-23-6 package size for space-constrained designs. Evaluate thermal management needs given the operating temperature range. Compare alternative switches if current availability is limited due to obsolescence status.
