DB-960-60W
60W / 26V / 925-960 MHz PA using 1x PD57070S The LdmosST FAMILY
PRELIMINARY DATA
N-CHANNEL ENHANCEMENT-MODE LATERAL MOSFETs * EXCELLENT THERMAL STABILITY * COMMON SOURCE CONFIGURATION * POUT = 60 W min. with 13 dB gain over 925 - 960 MHz * 10:1 LOAD VSWR CAPABILITY * BeO FREE AMPLIFIER.
DESCRIPTION The DB-960-60W is a common source N-Channel enhancement-mode lateral Field-Effect RF power amplifier designed for GSM / GPRS / EDGE base station applications. The DB-960-60W is designed in cooperation with Europeenne de Telecommunications S.A (www.etsa.fr), for high gain and broadband performance operating in common source mode at 26 V, capable of withstanding load mismatch up to 10:1 all phases and with harmonics lower than 30 dBc.
