Silicon SPDT Switch, Nonreflective, 100 MHz to 44 GHz

The ADRF5026 is a nonreflective, single-pole, double-throw (SPDT) radio frequency (RF) switch manufactured in a silicon process.

The ADRF5026 operates from 100 MHz to 44 GHz with better than 3.8 dB of insertion loss and 45 dB of isolation. The ADRF5026 features an all off control, where both RF ports are in an isolation state. The ADRF5026 has a nonreflective design and both of the RF ports are internally terminated to 50 Ω.

The ADRF5026 requires a dual-supply voltage of +3.3 V and −3.3 V. The device employs complimentary metal-oxide semiconductor/low-voltage transistor-transistor logic (CMOS/LVTTL) logic-compatible controls.

The ADRF5026 is pin-compatible with the ADRF5027 low frequency cutoff version, which operates from 9 kHz to 44 GHz.

The ADRF5026 RF ports are designed to match a characteristic impedance of 50 Ω. For ultrawideband products, impedance matching on the RF transmission lines can further optimize high frequency insertion loss and return loss characteristics. Refer to the Narrow-Band Impedance Matching section for an example of a matched circuit that achieves a flat insertion loss response of 2.4 dB from 28 GHz to 43 GHz.

The ADRF5026 comes in a 20-terminal, 3 mm × 3 mm, RoHS-compliant, land grid array (LGA) package and can operate from −40°C to +105°C.

The ADRF5026 supports defense and aerospace applications (AQEC).
