SKY12334-362LF

Attenuators Overview

The SKY12334-362LF is a GaAs FET-based 5-bit digital attenuator manufactured by Skyworks Solutions Inc. It operates within a frequency range of 500 MHz to 4 GHz with a nominal 50 Ohm impedance. The device features a least significant bit (LSB) step size of 0.5 dB and provides a maximum attenuation of 15.5 dB. It utilizes a Si serial-to-parallel driver interface for control. The component is housed in a 24-pin VFQFN exposed pad package and supports an insertion loss of approximately 2.7 dB.

Attenuators Feature Summary

• Utilizes GaAs FET technology for high-performance RF signal attenuation
• Integrates a Si serial-to-parallel driver for simplified digital control
• Provides precise 5-bit resolution with 0.5 dB LSB steps
• Operates reliably across a wide temperature range from -40°C to +85°C

Attenuators Applications

• RF front-end modules requiring variable gain control
• Wireless communication base stations
• Test and measurement equipment calibration circuits

Attenuators Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm end-of-life status and availability through authorized distributors, as discontinuation notifications may impact long-term supply chain stability for production units.

Attenuators Selection Notes

Select this component when a compact, low-loss digital attenuator is needed for frequencies up to 4 GHz. The 24-pin QFN package suits space-constrained designs. Ensure the driving circuitry matches the Si serial-to-parallel interface specifications for proper logic level translation and timing.

Attenuators Part Context

This part belongs to Skyworks' portfolio of RF attenuators designed for wireless infrastructure. It complements other models like the SKY12345-362LF and SKY12343-364LF, offering a balance between attenuation range and form factor for integrated RF systems.

Attenuators Replacement Considerations

The SKY12345-362LF serves as a public confirmed substitute with similar 15.5 dB attenuation and 24-QFN packaging. Verify pinout compatibility and interface voltage levels before substitution.
