of the new Triniti DX Pro™ amplifier family whose members

are pin-compatible and all operate under 3.5V bias voltage. The

CMM0530-LC is packaged in a low-cost, plastic, LCC-8 power

package. It has low thermal impedance and low RF loss. The

device requires minimum amount of external biasing and RF

matching circuits.

Description

The CMM0530-LC is a highly efficient multi-mode

power amplifier GaAs MMIC intended for use in portable tele-

phone handsets and data communications products for wireless

communications. It meets the handset requirements for cellular

AMPS, and the CDMA and TDMA digital standards for the US

cellular wireless communications. CMM0530-LC is a member

with appropriate resistor divider networks, when necessary, in

order to adjust the quiescent currents to within 10 mA of the

targeted values. As an example, for CDMA applications the tar-

get quiescent current of the second FET is 120 mA, while that

of the first is 50 mA. The total quiescent is 170 mA. It is also

recommend that the quiescent currents be set in the following

sequence: the second stage FET is set first, followed by the first

stage FET. The negative supply voltages control the quiescent

currents through each FET and, therefore, control the output

power, adjacent channel power ratio, and the currents at full

output power.

Application Information

The CMM0530-LC is a two-stage amplifier that requires

both positive and negative power supplies for proper operation.

It is essential that the negative supply be applied first during

turn-on and last during turn-off. Otherwise, the device may be

damaged.

The CMM0530-LC can be operated over a wide range of

positive and negative voltages to obtain various power, linearity

and efficiency performance. However, it is important to keep

the maximum DC power and the bias voltages within the speci-

fied absolute maximum rating to prevent over stressing the

device either electrically or thermally.

The positive supply voltages are applied to Pins 5, 6 and 7.

It is very important to provide adequate de-coupling

between the RF and the DC signals in designing the DC bias

circuit. Inadequate by-pass capacitance around the DC supply

lines and inductance can compromise the adjacent channel

power ratio (ACPR), or reduce power gain and/or create oscil-

lations. The recommend DC by-pass capacitance and low-pass

Design Considerations

Biasing Negative gate voltages are necessary to set the bias

currents of the two FET stages in the CMM0530-LC. The first

stage gate bias voltage is applied to Vg1 (Pin 2). The second

stage gate bias voltage is applied to Vg2 (Pin 1). It is desirable

to use one or more DACs (digital to analog converters) along
