Designed primarily for use in DECT, Japan Personal Handy System (PHS)
and other wireless Personal Communication Systems (PCS) applications.
The MRFIC1807 includes a single–stage power amplifier and transmit/receive
switch in a low–cost SOIC–16 package. The amplifier portion employs a
depletion mode power GaAs MESFET and produces up to +27 dBm output
with +19 dBm input. On–chip power control circuitry allows bias adjustment for
optimum performance. The T/R switch is capable of handling up to +28 dBm
through the transmit path without significant increase in insertion loss. The
switch is controlled by CMOS logic level signals — no negative control voltage
required. The MRFIC1807 is sized to be driven by the MRFIC1806 Driver/
Ramp IC.

Together with the rest of the MRFIC1800 GaAs ICs, this family offers the
complete transmit and receive functions, less LO and filters, needed for a
typical 1.8 GHz cordless telephone.

• Usable 1500–2200 MHz

• 8.0 dB Gain Including Switch

• +26 dBm Minimum Output Power at Antenna Port

• 1.0 dB Typ RX Path Insertion Loss

• Simple Off–Chip Matching for Maximum Flexibility

• 3.0 to 5.0 V Supply

• No Spurious Outputs for Load VSWR up to 8:1

• CMOS Level Switching Signal for T/R Switch

• Order MRFIC1807R2 for Tape and Reel.

R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.

• Device Marking = M1807
