Introduction

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. 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.
