General Description
The CMM3566-LC is a 7.0V, +24 dBm, linear power amplifier
intended for use in PCS handsets and wireless local loop
subscriber units and base stations. The amplifier is biased to meet
the requirements of linear modulation systems of W-CDMA. The
CMM3566-LC is packaged in a low-cost, space efficient, power
package that provides excellent electrical stability and low
thermal resistance. The part requires minimal external circuitry for
bias and matching to reduce space and cost.

Application Information
The CMM3566-LC is a three stage amplifier that requires a
positive and a negative supply voltages for proper operation. It is
essential when turning on the device that the negative supply be
applied before the positive supply. When turning the device off,
the positive supply should be removed before the negative supply
is removed.
The CMM3566-LC can be operated over a range of supply
voltages and bias currents. It is important that the maximum power
dissipation specification for the package be observed at all times
and that the maximum voltage across the device not be exceeded.
supply voltage is applied to pins 5, 6, 7 and 8. The negative volt-
age supplies control the quiescent current of the device. The quies-
cent current needs to be set at the level specified in order to get the
guaranteed RF performances.
Negative bias voltages can also be used to control the gain,
the output power and the operating current during operation of the
device.
Matching Circuits
Output matching circuit is required to achieve
the output power and gain guaranteed. Mimix’s recommenda-
tion for the topology of the matching circuit is shown in the
schematic diagram of the test circuit in this data sheet.
In providing both the negative and positive bias voltages, it is
important to provide adequate de-coupling between the RF signal
and the DC voltages. Inadequate de-coupling could result in low
output power, low gain or oscillation. Mimix recommends the
bias circuits shown in the evaluation circuit .

Circuit Design Considerations
Biasing
Three negative voltages are needed to set the bias current
of the 3-stage GaAs FET power amplifier. The first stage bias is
controlled via Vg1. The second stage bias is controlled via Vg2.
The output stage is controlled via Vg3. The recommended divider
networks for each gate bias shown in the schematic. The positive

Modulation
When biased as specified, the CMM3566-LC will
achieve the required adjacent channel response for the W-CDMA
linearity. Mimix tests each product under digital modulation to
ensure compliance to system specifications.
