RI23110
CDMA PCS 3–4 Volt Power Amplifier (1720–1910 MHz)
The RI23110 Personal Communications Service (PCS) Power Amplifier is a fully
matched 6-pin LCC surface mount module developed for PCS and wireless local
loop applications. This small and efficient Power Amplifier packs a full 1720–1910
MHz bandwidth coverage into a single compact package. This device meets the
stringent spectral linearity requirements of Code Division Multiple Access (CDMA)
PCS transmission, with high power added efficiency for power output of up to 29
dBm. A single GaAs Microwave Monolithic Intergrated Circuit (MMIC) contains all
active circuitry in the module. The MMIC contains on-board bias circuitry, as well as
input and interstage matching circuits. The output match is realized off-chip within
the module package to optimize efficiency and power performance into a 50 Ω load.
This device is manufactured with Conexant’s GaAs HBT process that provides for all
positive voltage DC supply operation while maintaining high efficiency and good
linearity. Primary bias to the RI23110 is supplied directly from a three-cell nickel
cadmium, single-cell lithium ion, or other suitable battery with output in the 3–4
volt range. Power down is accomplished by setting the voltage on the low current
reference pin to zero volts. No external supply side switch is needed as typical “off”
leakage is a few microamperes with full primary voltage supplied from the battery.

Evaluation Board Design
The evaluation board is a platform for testing and interfacing design circuitry. To accommodate the
interface testing of the RI23110, the evaluation board schematic and diagrams are provided for
preliminary analysis and design. Figure 19 shows the basic schematic of the board for the 1720
MHz to 1910 MHz range. Figure 20 illustrates the board layout.

Because this device package is sensitive to moisture absorption, it is baked and vacuum packed
prior to shipment. Instructions on the shipping container label regarding exposure to moisture after
the container seal is broken must be followed. Otherwise, problems related to moisture absorption
may occur when the part is subjected to high temperature during solder assembly. If the part is
attached in a reflow oven, the temperature ramp rate should not exceed 5 °C per second. Maximum
temperature should not exceed 225 °C and the time spent at a temperature exceeding 210 °C should
be limited to less than 10 seconds. If the part is manually attached, precaution should be taken to
insure that the part is not subjected to a temperature exceeding 300 °C for more than 10 seconds.
For additional details on both attachment techniques, please refer to Application Note: GaAs IC
Handling, Document Number AN-0004.

Electrostatic Discharge Sensitivity RI23110

Electrostatic Discharge Sensitivity
The RI23110 is a Class I device. Figure 24 lists the Electrostatic Discharge (ESD) immunity level
for each pin of the RI23110 product. The voltages shown in Figure 24 specify the ESD threshold
level for each pin where the I-V curve between the pin and ground starts to show degradation. The
ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human
Body Model. Since 2000 volts represents the maximum measurement limit of the test equipment
used, pins marked > 2000 V pass 2000V ESD stress.
Various failure criteria can be utilized when performing ESD testing. Many vendors employ
relaxed ESD failure standards which fail devices only after “the pin fails the electrical specification
limits” or “the pin becomes completely non-functional”. Conexant employs the most stringent
criteria and fails devices as soon as the pin begins to show any degradation on a curve tracer.
To avoid ESD damage, latent or visible, it is very important that the product assembly and test
areas follow the Class-1 ESD handling precautions listed in Table 9.
