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.
