The MRFIC Line
1800 MHz GaAs Integrated
Power Amplifier
Designed specifically for application in Pan European digital 1.0 watt DCS1800
handheld radios, the MRFIC1818 is specified for 33 dBm output power with power
gain over 30 dB from a 4.8 volt supply. With minor tuning changes, the MRFIC1818
can be used for PCS1900 as well as PCS CDMA. To achieve this superior
performance, Motorola’s planar GaAs MESFET process is employed. The device
is packaged in the PFP–16 Power Flat Package which gives excellent thermal
and electrical performance through a solderable backside contact while allowing
the convenience and cost benefits of reflow soldering.
