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 an 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.
