SAV-331+

Overview

The SAV-331+ is a depletion-mode pseudomorphic high-electron-mobility transistor (D-PHEMT) MMIC designed for ultra-low noise and medium current applications. It operates within a frequency range of 10 to 4000 MHz and is housed in a compact SOT-343 package. The device requires external biasing and impedance matching networks. Key electrical specifications include a typical noise figure of 0.5 dB at 300 MHz, a gain of 24.1 dB at the same frequency, an output IP3 of +32.3 dBm, and a P1dB compression point of +19.6 dBm. It functions with a drain-source voltage of 4 V and a quiescent current of 60 mA.

Feature Summary

• Utilizes D-PHEMT technology to achieve extremely low noise figures across a wide bandwidth.
• Provides high gain and superior linearity metrics suitable for sensitive receiver front-ends.
• Operates with low power consumption through a medium current drain requirement.
• Packaged in a miniature surface-mount format to facilitate dense circuit board layouts.

Applications

• Cellular communication systems
• ISM band applications
• GSM infrastructure
• WCDMA networks
• WiMax and WLAN implementations

Procurement Notes

Verify RoHS compliance by confirming the presence of the plus suffix in the part number. Ensure that the procurement includes necessary external components for biasing and impedance matching, as the device does not contain integrated matching circuits. Confirm the specific reel quantity required matches the available standard packaging options provided by the manufacturer.

Selection Notes

Select this component when system requirements demand minimal signal degradation in the 10 to 4000 MHz range. It is appropriate for designs where low noise figure is critical for receiver sensitivity. Designers must account for the need for external DC biasing and RF matching networks. Consider the thermal resistance and operating temperature limits during layout planning.
