Designed primarily for use in wireless Personal Communication Systems
(PCS) applications such as Digital European Cordless Telephone (DECT),
Japan’s Personal Handy System (PHS) and the emerging North American
systems. The MRFIC1813 is also applicable to 2.4 GHz ISM equipment. The
device combines a balanced upmixer and a transmit exciter amplifier in a
low-cost TSSOP–16 package. Minimal off-chip matching is required while
allowing for maximum flexibility and efficiency. The mixer is optimized for
low–side injection and provides more than 12 dB of conversion gain with over 0
dBm output at 1 dB gain compression. Image filtering is implemented off-chip to
allow maximum flexibility. A CMOS compatible ENABLE pin allows standby
operation where the current drain is less than 250 mA.

Together with other devices from the MRFIC180X or the MRFIC240X series,
this GaAs IC family offers the complete transmit and receive functions, less LO
and filters, needed for a typical 1.8 GHz cordless telephone or 2.4 GHz ISM
band equipment.

• Usable Frequency Range = 1.7 to 2.5 GHz

• 15 dB Typ IF to RF Conversion Gain

• 3 dBm Power Output Typ, 0 dBm Minimum at 1 dB Gain Compression

• Simple Off-chip Matching for Maximum Flexibility

• Low Power Consumption = 75 mW (Typ)

• Single Bias Supply = 2.7 to 4.5 Volts

• Low LO Power Requirement = – 5 dBm (Typ)

• Low Cost Surface Mount Plastic Package

• Order MRFIC1813R2 for Tape and Reel.

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

• Device Marking = M1813
