The MRFIC Line

1.8 GHz PA Driver/Ramp

Designed primarily for use in DECT, Japan Personal Handy System (PHS),

and other wireless Personal Communication Systems (PCS) applications. The

MRFIC1806 includes a two stage driver amplifier and transmit waveform

shaping circuitry in a low–cost SOIC–16 package. The amplifier portion

employs depletion mode power GaAs MESFETs to produce +21 dBm output

with 0 dBm input. The ramping circuit controls the burst–mode transmit rise and

fall time and is adjustable through external components. This circuitry also

places the amplifier in standby during TDMA receive mode. The MRFIC1806 is

sized to drive the MRFIC1807 PA/Switch.

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 – 2500 MHz

• 23 dB Typical Gain

• +21 dBm Typical 1.0 dB Compression

• Simple Off–Chip Matching for Maximum Flexibility

• 3.0 to 5.0 Volt Supply

• Low Cost Surface Mount Plastic Package

• Order MRFIC1806R2 for Tape and Reel.

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

• Device Marking = M1806
