GENERAL DESCRIPTION

The ADRF5027 is a nonreflective, single-pole, double-throw

(SPDT) radio frequency (RF) switch manufactured in a silicon

process.

The ADRF5027 operates from 9 kHz to 44 GHz with better

than 3.8 dB of insertion loss and 43 dB of isolation. The

ADRF5027 features an all off control, where both RF ports are

in an isolation state. The ADRF5027 has a nonreflective design

and both of the RF ports are internally terminated to 50 Ω.

The ADRF5027 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 ADRF5027 is pin compatible with the ADRF5026 fast

switching version, which operates from 100 MHz to 44 GHz.

The ADRF5027 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 low insertion loss

response of 2.2 dB from 28 GHz to 43 GHz.

The ADRF5027 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.
