Description
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.
The CMM3566-LC is a 7.0 V, +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.

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.
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
3236 Scott Boulevard
Santa Clara, California 95054
supply voltage is applied to pins 5, 6, 7 and 8. The negative voltage supplies control the quiescent current of the device. The quiescent 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. Celeritek’s recommendation 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. Celeritek recommends the
bias circuits shown in the evaluation circuit .
