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. Refer to the Electrical Specifications section, Typical Performance Characteristics section, and Applications Information section for more details.
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.

Markets & Technology
Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
ADRF5025-EVALZ is a fully populated, connectorized evaluation board using 4-layer, 62 mil thick, RO4003 PCB material.
For normal operation, two supply voltages +3.3V and -3.3V should be applied to the VDD and VSS test points respectively, while their ground voltages are connected to the GND test point. Control input voltage, 0V or +3.3V, should be applied to the CTRL test point to select the switch state between RFC-RF1 and RFC-RF2.
The RF input signal can be applied at the edge-launch, 2.4 mm RF connector labeled RFC and the RF output signals can be measured at the edge-launch, 2.4 mm connectors labeled RF1 and RF2.
Tools & Simulations
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
