Additional Details

The HMC187MS8TR is a non-reflective SPDT (Single Pole Double Throw) switch fabricated using a GaAs MMIC process. It operates over a broad frequency range, typically from DC to 3 GHz, and is controlled by a positive voltage. The non-reflective design ensures that the impedance is well-matched in both the on and off states, minimizing signal reflections and improving overall system performance. The switch is housed in a small 8-lead MSOP (Mini Small Outline Package), making it suitable for compact designs.

The typical insertion loss is 0.7 dB at 3 GHz, and the isolation is 35 dB at 3 GHz. The switching speed is typically 3 ns. The control voltage range is +3V to +8V. This switch is designed to provide reliable performance in demanding RF and microwave applications, where low insertion loss, high isolation, and fast switching speed are critical requirements.
