DISCRETE SEMICONDUCTORS DATA SHEET M3D427 BLF2048 UHF push-pull power LDMOS transistor Preliminary specification Supersedes data of 1999 Dec 01 2000 Feb 17 Philips Semiconductors Preliminary specification UHF push-pull power LDMOS transistor FEATURES High power gain Easy power control Excellent ruggedness Source on underside eliminates DC isolators, reducing common mode inductance Designed for broadband operation (HF to 2.2 GHz). APPLICATIONS Common source class-AB operation for PCN and PCS applications in the 1800 to 2200 MHz frequency range. DESCRIPTION Push-pull silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 4-lead flange package (SOT539A) with a ceramic cap. The common source is connected to the mounting flange. QUICK REFERENCE DATA RF performance at Th = 25 °C in a common source test circuit.
