Key Differentiators
- Broadband DC to 8 GHz coverage (vs HMC284AMS8GE)
- High isolation up to 70 dB (vs HMC284AMS8GE)
- Non-reflective design (vs HMC270MS8GETR)
Design Notes
Ensure RF traces are impedance-matched to 50 ohms. Use controlled impedance traces and place the switch close to the antenna or transceiver to minimize trace length. The exposed pad should be soldered to a ground plane with multiple vias for thermal and electrical grounding.
The control voltage is -5 V. Ensure a clean, well-decoupled -5 V supply. Place a 100 nF capacitor close to the VCTL pin to filter noise. The switch does not require a positive supply, simplifying the power design.
Do not exceed the maximum RF input power, which is typically 27 dBm. Exceeding this can damage the switch. Also, ensure the control voltage is within the specified range to avoid latch-up or damage. For positive control applications, use the HMC284AMS8GE instead.
