Overview
The ADG901BCPZ-REEL7 is a wideband RF switch IC manufactured by Analog Devices Inc., housed in an 8-LFCSP (3x3) package. It features a single-pole single-throw (SPST) configuration with a 50 Ohm termination, designed for general-purpose RF applications. The device operates within a frequency range of 0 Hz to 4.5 GHz, supporting signals up to 2.5 GHz effectively. Key electrical parameters include an insertion loss of 0.8 dB and typical off-isolation of 40 dB at 1 GHz. It functions on a supply voltage of 1.65 V to 2.75 V and withstands temperatures from -40°C to +85°C.
Feature Summary
- Provides high isolation performance suitable for RF signal routing
- Supports wideband operation across microwave frequencies
- Integrates 50 Ohm termination for impedance matching
Applications
- RF signal switching in communication systems
- Test and measurement equipment signal paths
- Wireless infrastructure component selection
Procurement Notes
Verify the specific suffix REEL7 against official Analog Devices documentation to confirm packaging format and reel specifications. Ensure compatibility with 1.65 V to 2.75 V supply rails during integration. Confirm that the 8-LFCSP footprint matches the target PCB layout constraints. Cross-reference the part number with current availability status as distribution channels may indicate limited stock or discontinuation risks.
Selection Notes
Select this component when designing circuits requiring low insertion loss and high isolation in compact form factors. The SPST topology simplifies control logic compared to multiplexer alternatives. Consider the narrow supply voltage range when designing power management sections. The LFCSP package offers thermal efficiency but requires precise soldering techniques for reliable surface mount assembly.
Part Context
This part belongs to the ADG901 series of CMOS RF switches from Analog Devices. It complements other analog switches by focusing specifically on radio frequency performance rather than baseband signal routing. The series emphasizes miniaturization while maintaining signal integrity for high-frequency applications.
Replacement Considerations
Check for ADG901BRMZ-REEL7 if different reel quantities are required. Verify ADG901BCPZ-500RL7 for alternative packaging options. Consult official substitution lists for pin-compatible upgrades.
