900 MHz image-reject receiver in 28-SSOP
The MAX2441EAI is a 900 MHz image-reject receiver from Analog Devices, designed to down-convert RF signals while suppressing the image frequency without an external SAW filter. The receiver integrates the mixer, LO buffer, and IF amplifier on a single die, reducing the external component count in the front-end signal chain.
Supply rail and temperature envelope
The supply voltage range of 2.7 V to 4.8 V allows the part to run directly from a regulated 3.3 V bus or a 5 V rail with margin. The 0/1 driver/receiver count confirms this is a single-channel receiver with no integrated line driver; the output is a baseband or IF signal intended for a downstream demodulator or ADC.
Active production — no obsolescence watch
The package is, not tape-and-reel. For automated pick-and-place, confirm the handling method with your assembly house — bulk tubes may require a tube feeder or manual loading.
Package and footprint notes
The 28-SSOP package (0.209-inch body width, 5.30 mm) has a 0.65 mm lead pitch typical of SSOP-28. The narrow body saves board area compared to a wider SOIC, but the fine pitch demands a controlled solder-paste stencil aperture to avoid bridging. RoHS non-compliant — the part contains lead in the solder finish. This is typical for legacy RF parts and may require an exemption for RoHS-regulated products. Confirm your assembly's exemption status before design-in.
