Compare high power PIN diode switches by frequency range, power handling, switching speed, insertion loss and isolation. Use the model table and linked documents to shortlist a high power RF switch, then confirm configuration, bias and control requirements, and operating conditions for your application. Include the model number and your requirements when requesting a quote.

View the low-power PIN diode switch page and prepare your application requirements.
Explore coaxial switch options and request model-specific information.
Review RF limiter options and prepare your component enquiry.
Explore RF terminations and the details to include in a load enquiry.
Define the signal path, operating conditions and control interface for your inquiry.
Specify the operating band, number of RF ports and required switching paths. Include connector types, impedance, enclosure dimensions and mounting constraints so the proposed model can be checked against your system.
Provide the required power level and operating mode, along with temperature range, mounting and available cooling. Include any mismatch, vibration or environmental requirements that need to be verified for the selected model.
State your available supply and logic levels, required switching time and control sequence. Confirm whether the selected model includes a driver or requires external bias and control circuitry.
Compare PIN diode switch specifications under the conditions your system will use. Start with the table, then check the selected model’s document and confirm any missing details before specifying the part.
Compare ratings only after checking the specified operating conditions. Ask whether the rating covers continuous-wave or pulsed operation, what temperature and mismatch limits apply, and whether switching with RF present is permitted. The catalog table alone does not establish these conditions for every model.
Suitability must be checked for the selected model and system. Include transmit power, receive-path loss, required isolation, switching sequence and receiver protection requirements in your inquiry. Confirm these together rather than treating a power rating alone as approval for T/R service.
Confirm whether the selected model needs an external driver or includes control circuitry. Ask for supply voltage and current, logic levels, bias requirements, connector or pin assignments, switching-time test conditions and power-up/power-down sequencing.
