VMMK-3803-BLKG

RF Amplifiers Overview

The VMMK-3803-BLKG is a monolithic microwave integrated circuit (MMIC) low-noise amplifier designed for 802.16 WiMAX applications. It operates within a frequency range of 3GHz to 11GHz, with performance testing conducted at 6GHz. The device provides a gain of 20dB and maintains a noise figure of 1.5dB. It features an output 1dB compression point (P1dB) of 9dBm. The amplifier requires a supply voltage between 3V and 5V, drawing a typical supply current of 20mA. It is housed in a surface-mount 0402 package.

RF Amplifiers Procurement Notes

This component is officially listed as obsolete by the manufacturer, with end-of-life notifications dating back to January 2016. Procurement must focus on verifying the authenticity of remaining stock from authorized distributors or surplus dealers. Buyers should request full traceability documentation and confirm that the units are new old stock rather than refurbished items. Due to the discontinued status, lead times may vary significantly, and long-term supply continuity cannot be guaranteed for new production runs.

RF Amplifiers Selection Notes

Engineers selecting this part must account for its discontinued status when designing new products. While the 0402 package offers space efficiency, alternative components with similar RF specifications but available supply chains should be evaluated. The specific 802.16 WiMAX optimization makes it suitable for legacy systems, but general-purpose LNAs might be more viable for new designs. Verify that the 3V to 5V supply range aligns with the system's power architecture before integration.
