FAQ(Frequent Asked Qestions)
Q: What RF switch configurations are available?
A: Below are our popular configurations for your reference, besides, we accept customization.
Electro-mechanical switches: 1P2T (single-pole, double-throw); 1P3T; 1P4T; 1P6T; 1P8T; 1P12T
Solid-state switches: 1P1T; 1P2T; 1P3T; 1P4T; 1P6T; 1P8T; 1P10T; 1P12T; 1P16T
Q: What control options are available?
A: Depending on model, EM RF switches offer TTL logic-level control, or +12, +15 or +28 V DC control. Solid-state switches use TTL logic levels, and one model has a USB interface.
Q: Are the RF switch attenuators bi-directional?
A: All of XINPOMING's RF switches are bi-directional unless noted differently on the specification sheet.
Q: I need a custom RF switch designed. How much are your typical NREs (non-recurring engineering charges)?
A: XINPOMING does not charge NREs. Please send your custom requirement to us for details communication.
Q: Are your 18GHz electro-mechanical switches available with indicators or as latching?
A: Typical options: latching, self-terminating, indicators, TTL, RoHS and non-RoHS.
