The F2971 is a rugged, low insertion loss, 75? SP2T (SPDT) absorptive RF switch designed for a wide 范围 of CATV and broadband RF 应用s. This device covers a broad 频率范围 from 5MHz to 3000MHz. In addition to having excellent linearity and isolation performance, it also provides a 75? termination to the isolated RF port. The F2971 特征 an internally switched termination resistor on the RF common port.

Evaluation Board for 75 Ohm SP2T Absorptive RF Switch
The F2971EVBI is a fully populated evaluation board enabling easy RF evaluation of the F2971 product.
“Thru” calibration connectors are conveniently located on the evaluation board to simplify the calibration process prior to making any RF measurements. The RF through measurement (RF1 to RF2) can be made by 申请ing the correct control logic voltage to the control pins as outlined in the 数据表. DC power, ground and the control voltages are applied to the pin header.
