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 multi-
carrier 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.
