GENERAL DESCRIPTION

The ADRF5420 is a reflective, SPDT switch manufactured in the

silicon process. This switch operates from 1GHz to 90GHz with

better than 3.0dB of insertion loss and 30dB of isolation. The

ADRF5420 has an RF input power handling capability of 24dBm for

the through path and 21dBm for hot switching.

The ADRF5420 draws a current of 130µA on the positive supply of

+3.3V and 490µA on negative supply of −3.3V. The device employs

complementary metal-oxide semiconductor (CMOS)-/low voltage

transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5420 can also operate with a single positive supply

voltage (VDD) applied while the negative supply voltage (VSS) is tied

to ground. The small signal performance is maintained while the

switching characteristics, linearity, and power handling performance

is derated. See Table 2 for more details.

The ADRF5420 RF ports are designed to match a characteristic

impedance of 50Ω. The ADRF5420 is a 30-ball, 1.56mm × 2.04mm,

bumped bare die sales and can operate between −40°C to +105°C.
