The MRFIC2006 is an Integrated P A designed for linear operation in the 800
MHz to 1.0 GHz frequency range. The design utilizes Motorola’s advanced
MOSAIC 3 silicon bipolar RF process to yield superior performance in a cost
effective monolithic device. Applications for the MRFIC2006 include CT-1 and
CT-2 cordless telephones, remote controls, video and audio short range links,
low cost cellular radios, and ISM band transmitters.

The MRFIC2006 was designed for low cost and flexibility.
Low cost was achieved by minimizing external components
and using an SOIC package. Flexibility was achieved by allowing the bias current to be externally adjustable resulting in
a broad range of output power capability . The bias pin can be
ramped to reduce AM splatter in TDD/TDMA systems and
can be used to trim the RF output power.
THEORY OF OPERATION
The input port is internally matched to 50 ohms. Return
loss is typically 15–16 dB in the 800 –1000 MHz range. The
output port is nearly 50 ohms but is an open collector and
therefore requires an external bias inductor. Using an RF
choke will result in a 1 1–12 dB output return loss. However , a
10 nH inductor will improve it to 15–20 dB. A 10 nH inductor
is small enough in value to be printed on the board. DC
blocks are required on the input and output. Values of 100 pF
are recommended.
Supply decoupling must be done as close to the IC as possible. A 1000 pF capacitor is recommended. A series RF
choke is recommended to keep the RF signal off the supply
line. A 10 nF decoupling capacitor is recommended on the
V
line but does not need to be very close to the IC.
bias
The V
VCC will maximize the bias current which will maximize linearity. Adding a series resistor will reduce the bias current
which will improve efficiency. Figure 9 shows the efficiency
versus output power with V
sistor will cause these curves to shift to the left. The RF output power can be trimmed by using a variable resistor. The

case of TDD/TDMA systems, to ramp the IC. By applying a
linear ramp voltage, such as the one provided by the
MRFIC2004, it has been demonstrated to meet the CT2
Common Air Interface splatter specifications.
The MRFIC2006 is internally temperature compensated.
For input powers of –5.0 to 0 dBm the output power temperature variation is typically less than 0.2 dB from –35 to +85°C.
