GENERAL DESCRIPTION

The ADRF5025 is a reflective single-pole double-throw (SPDT)

switch, manufactured in silicon process.

This switch operates from 9 kHz to 44 GHz with better than

1.6 dB of insertion loss and 35 dB of isolation. The ADRF5025

has an radio frequency (RF) input power handling capability of

27 dBm for both the through path and hot switching.

The ADRF5025 draws a low current of 14 µA on the positive

supply of +3.3 V and 120 µA on negative supply of −3.3 V. The

device employs complementary metal-oxide semiconductor

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

compatible controls.

The ADRF5025 is pin compatible with the ADRF5024, low

frequency cutoff version, which operates from 100 MHz to

44 GHz.

The ADRF5025 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 Electrical Specifications section, Typical Performance

Characteristics section, and Applications Information section

for more details.

The ADRF5025 comes in a 2.25 mm × 2.25 mm, 12-terminal,

RoHS-compliant, land grid array (LGA) package and can

operate from −40°C to +105°C.
