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

APPLICATIONS INFORMATION

DESIGN CONSIDERATIONS

The MRFIC1813 combines a single–balanced MESFET
mixer with an exciter amplifier. It is usable for transmit fre­quencies from 1.7 to 2.5 GHz and IF frequencies from 70 to
350 MHz. The design is optimized for low–side local oscilla­tor injection in hetrodyne transmit applications.

Minimal off–chip matching is required while allowing for
flexibility and performance optimization. An active balun is
employed at the IF port which gives good balance down to at
least 70 MHz. A passive splitter is used at the LO input to
complete the single–balanced configuration.

CIRCUIT CONSIDERATIONS

Figure 1 shows the application circuit used to gather the
data presented in the characterization curves. As shown in
Table 1, the IF port impedance is very high. Three hundred
ohms was chosen for R1 to shunt the IF port as a compro­mise of gain and bandwidth. A 50 Ω resistor can be used and
L1 and C5 eliminated to provide a broadband match. The

conversion gain is reduced to about 8 dB. Microstrip induc­tors T1 and T2 combine with inductance internal to the de­vice to form RF chokes. Some tuning of the RF output can be
achieved with T1.

As with all RF devices, circuit layout is important. Con­trolled impedance lines should be used for all RF and IF in­terconnects. As shown in Figure 1, power supply by–passing
should be used to avoid device instability. Ground vias
should be included near all ground connections indicated in
the schematic. Off–chip components should be mounted as
close to the IC leads as possible.

EVALUATION BOARDS

Evaluation boards are available for RF Monolithic Inte­grated Circuits by adding a “TF” to the device type. For a
complete list of currently available boards and one in devel­opment for newly introduced products, please contact your
local Motorola Distributor or Sales Office.
