GENERAL DESCRIPTION The ADRF5024 is a reflective, single-pole double-throw (SPDT) switch manufactured in the silicon process. This switch operates from 100 MHz to 44 GHz with better than 1.7 dB of insertion loss and 35 dB of isolation. The ADRF5024 has a radio frequency (RF) input power handling capability of 27 dBm for both the through path and hot switching. The ADRF5024 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 ADRF5024 is pin-compatible with the ADRF5025, low frequency cutoff version, which operates from 9 kHz to 44 GHz. The ADRF5024 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 ADRF5024 comes in a 2.25 mm × 2.25 mm, 12-terminal, RoHS-compliant, land grid array (LGA) package and can operate between −40°C to +105°C. Rev.
