The MRFIC0904 is an integrated driver amplifier designed for class A/B
operation in the 800 MHz to 1 GHz frequency range. The design utilizes
Motorola’s Advanced GaAs FET process to yield superior performance and
efficiency in a cost effective monolithic device. Off–chip output matching pro­vides maximum flexibility in design. Applications for the MRFIC0904 include
GSM, AMPS, and ISM band transmitters.

APPLICATIONS INFORMATION

DESIGN PHILOSOPHY

The MRFIC0904 is a versatile driver amplifier designed to
operate in the 800 MHz to 1 GHz frequency range for cellular
phone and Industrial, Scientific, and Medical (ISM) applica­tions. The amplifier is designed using depletion mode GaAs
MESFETs to perform at high efficiency at battery voltages of

3.6 and 4.8 Volts. While designed as a driver amplifier for a
discrete transistor final stage, the device can act as a power
amplifier for lower power systems such as ISM applications
in telemetry and cordless telephones.

THEORY OF OPERATION

The MRFIC0904 has various control features making it ver­satile and applicable to both linear and saturated applications.
The BIAS pin allows the setting of drain quiescent current. For
non–linear applications such as GSM cellular, the pin can be
grounded. For better gain and linearity, a positive voltage up
to about 0.6 Volts can be applied. The PCNTRL pin allows

the control of the output power over a wide dynamic range
with low AM to AM distortion such as is required in GSM and
other cellular systems. As shown in Figures 6 through 9,
PCNTRL affects both the output power and the drain current
thus maintaining good efficiency over a range of output pow­er. The ENABLE pin is used to control the on–of f state of the
device and is useful as a reduced current standby control. A
logic high signal of more than 2.5 Volts turns the device on. A
logic low signal of less than 0.5 Volts reduces total supply
current to typically less than 200 µA.

EVALUATION BOARDS

Evaluation boards are av ailable for RF Monolithic Inte­grated Circuits by adding a “TF” suffix to the device type.
