BLP35M805Z

Overview

The BLP35M805 is a 5 W LDMOS power transistor designed for high-power continuous wave applications across the HF to 3500 MHz frequency range. It operates with a drain-source voltage of up to 65 V and features an integrated electrostatic discharge protection circuit. The device utilizes a thermally enhanced HVSON16 package (SOT1371-1) with dimensions of 4 x 6 x 0.85 mm. In class-AB operation at 2450 MHz, it delivers 5 W output power with 20 dB gain and 50% drain efficiency. At 3500 MHz, it maintains 5 W output with 9.6 dB gain and 33% efficiency under specified bias conditions.

Feature Summary

Procurement Notes

Verify component authenticity by checking the manufacturer's official documentation against the physical marking on the SOT1371-1 package. Ensure that the ordering suffix matches the specific revision required for your design. Confirm RoHS compliance status directly from the supplier's current product declaration before finalizing procurement orders.

Selection Notes

Select this component for single-ended amplifier designs requiring robust performance in the HF to 3500 MHz spectrum. Evaluate thermal management requirements carefully, as the junction-to-case thermal resistance dictates the necessary heatsinking strategy. Ensure the application circuit supports the specified gate-source threshold voltage and biasing conditions for optimal linearity.
