GENERAL DESCRIPTION
The ADRF5025 is a reflective single-pole double-throw (SPDT)
switch, manufactured in silicon process.
The ADRF5025 is pin compatible with the ADRF5024, low
frequency cutoff version, which operates from 100 MHz to
44 GHz.
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 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 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 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.
