ADG901SCPZ-EP-RL7

Overview

The ADG901SCPZ-EP-RL7 is a wideband, single-pole single-throw (SPST) RF switch manufactured by Analog Devices Inc. utilizing a CMOS process. It operates as an absorptive switch with 50 Ω terminated shunt legs, providing high isolation and low insertion loss across a frequency range from DC to 4.5 GHz. The device features 40 dB off-isolation at 1 GHz and 0.8 dB insertion loss at 1 GHz. It functions on a single power supply ranging from 1.65 V to 2.75 V with power consumption below 1 μA. Control inputs are compatible with both CMOS and LVTTL logic levels. The component is housed in an 8-lead LFCSP package measuring 3 mm × 3 mm.

Feature Summary

• Absorptive SPST design with 50 Ω terminated shunt legs for consistent impedance matching
• Wideband operation supporting frequencies up to 4.5 GHz with -3 dB bandwidth
• Integrated CMOS control logic eliminating the need for external driving circuitry
• Ultra-low power consumption suitable for battery-operated wireless applications

Applications

• Wireless communications systems
• Digital transceiver front-end switching
• Antenna diversity switching modules
• High-speed filter selection circuits

Procurement Notes

Verify that the suffix EP indicates enhanced product specifications or reliability standards compared to standard commercial variants. Confirm the RL7 designation corresponds to the specific reel packaging configuration required for automated assembly processes. Ensure compatibility with the 3 mm x 3 mm LFCSP footprint during PCB layout validation. Cross-reference the datasheet revision to confirm current electrical parameter limits before finalizing procurement orders.

Selection Notes

Select this component when an absorptive topology is required to minimize signal reflections in high-frequency circuits. The integrated 50 Ω termination distinguishes it from reflective switches like the ADG902. Consider the low voltage operation and minimal control current for energy-constrained designs. Verify that the 3 mm x 3 mm package size fits within the available board space constraints of the target application.

Part Context

This part belongs to the ADG901 family of wideband CMOS RF switches. The base model provides general-purpose switching capabilities, while the EP variant typically denotes enhanced performance or reliability characteristics. The RL7 suffix specifies the tape and reel packaging format used for surface-mount technology assembly lines. This series is designed to replace discrete RF components with integrated solutions.

Replacement Considerations

The ADG901BCPZ-RL7 serves as a standard commercial equivalent without the EP enhancement. For reflective switching requirements instead of absorptive, the ADG902 series is the functional counterpart. Direct pin-compatible replacements may require verification of insertion loss and isolation parameters against specific system requirements.
