The ADRF5026 is a nonreflective, single-pole, double-throw (SPDT) radio frequency (RF) switch manufactured in a silicon process.
The ADRF5026 operates from 100 MHz to 44 GHz with better than 3.8 dB of insertion loss and 45 dB of isolation. The ADRF5026 features an all off control, where both RF ports are in an isolation state. The ADRF5026 has a nonreflective design and both of the RF ports are internally terminated to 50 Ω.
The ADRF5026 requires a dual-supply voltage of +3.3 V and −3.3 V. The device employs complimentary metal-oxide semiconductor/low-voltage transistor-transistor logic (CMOS/LVTTL) logic-compatible controls.
The ADRF5026 is pin-compatible with the ADRF5027 low frequency cutoff version, which operates from 9 kHz to 44 GHz.
The ADRF5026 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 Narrow-Band Impedance Matching section for an example of a matched circuit that achieves a flat insertion loss response of 2.4 dB from 28 GHz to 43 GHz.
The ADRF5026 comes in a 20-terminal, 3 mm × 3 mm, RoHS-compliant, land grid array (LGA) package and can operate from −40°C to +105°C.

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)
ADRF5026-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. Two control input voltages, 0/+3.3V, should be applied to EN and CTRL test points to select the switch state between RFC-RF1, RFC-RF2 and all-off.
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
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.
