GENERAL DESCRIPTION

The ADRF5080 is a reflective, SP8T switch manufactured in the

silicon process. The ADRF5080 operates from 100 MHz to 20 GHz

with an insertion loss of lower than 2.0 dB and an isolation higher

than 40 dB. The device has an RF input power handling capability

of 30 dBm continuous wave power for the insertion loss path.

The ADRF5080 operates with a dual-supply voltage, +3.3 V and

−3.3 V. The device can also operate with a single-supply voltage

(VDD) applied while the negative supply pin (VSS) is tied to ground.

The single-supply operation condition requires a lower operating

power while the excellent small signal performance is maintained

See Table 2 for details.

The ADRF5080 employs complementary metal-oxide semiconduc-

tor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-com-

patible controls.

The ADRF5080 comes in a 36-terminal, 5.50 mm × 5.50 mm, RoHS

compliant, land grid array (LGA) package and can operate from

−40°C to +105°C.
