BLP9LA25SZ

Overview

The Ampleon BLP9LA25SZ is a 13.6 V, 25 W Power LDMOS transistor designed for land mobile radio applications supporting frequencies from HF up to 941 MHz. It operates in TO-270-2F-1 packages with drain connected to the flange. Key electrical parameters include a maximum drain-source voltage of 40 V and a junction temperature limit of 225 °C. At 520 MHz with 25 W output power, it delivers typical power gain of 18.8 dB and drain efficiency of 72%. Thermal resistance from junction to case is 0.6 K/W at Tcase = 80 °C.

Feature Summary

• Integrated dual-sided ESD protection
• Extreme ruggedness rated at 65:1 VSWR
• High linearity performance

Applications

• TETRA, SSB and LTE mobile radio applications in VHF and UHF bands
• Wideband radio applications in the 380 MHz to 460 MHz range
• Wideband radio applications in the 800 MHz to 870 MHz range

Procurement Notes

Verify the specific ordering suffix against the official Ampleon datasheet before procurement. The 'Z' suffix indicates a tape and reel packing format (TR13) with a minimum orderable quantity of 500 pieces. Confirm that the package variant matches the required pinout configuration for the target circuit design.

Selection Notes

Select this component for wideband land mobile radio designs requiring high efficiency and extreme load mismatch tolerance. Ensure the thermal management system maintains the case temperature within limits to support the specified 225 °C junction temperature rating during continuous operation.

Part Context
