Model SM08790-47LDL 869-896 MHz 50 Watt Linear Power Amplifier FOR GSM APPLICATIONS The SM08790-47LDL is an 869-896 MHz solid state LDMOS amplifier designed for the Cellular/GSM telephony market. Its compact size and ultra high linearity make it ideally suited for systems using CDMA, TDMA, or any high dynamic range multicarrier applications. The P1dB is +47 dBm, the linear gain is 51 dB, and the gain change over temperature is only ± 0.5 dB. Stealth Microwave’s proprietary predistortion technique allows for an OIP3 of +66 dBm. The unit comes standard in modular form or as a rack mountable amplifier.
