Designed specifically for application in Pan European digital 1.0 watt
DCS1800/PCS1900 handheld radios, the MRFIC1817 is specified for 32 dBm
output power with power gain over 27 dB from a 3.6 volt supply . 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.

• Minimum Output Power Capabilities

32 dBm @ 3.6 Volts
30 dBm @ 3.0 Volts

• Typical Volt Characteristics

RF Input Power = 5.0 dBm
RF Output Power = 33.5 dBm
Typical PAE = 42%

• Low Current required from Negative Supply – 2 mA max

• Guaranteed Stability and Ruggedness

• Order MRFIC1817R2 for Tape and Reel.

R2 Suffix = 1,500 Units per 16 mm, 13 inch Reel.

• Device Marking = M1817
