DATA SHEET
CX65105: 1700 – 2200 MHz Linear Power Amplifier
Applications
• PCS/DCS/UMTS
• Repeaters
• WLL and ISM bands
• Mobile radio
• Telematics
Features
• Typical POUT of 28.5 dBm
• High linearity
• Low power consumption
• Single +5 V supply
• LCC (8-pin, 8 x 8 mm) package
Description
Skyworks CX65105 Power Amplifier (PA) is a fully matched, 8-pin
Leadless Chip Carrier (LCC) surface mount module, developed for
Personal Communications System (PCS), Digital Communications
System (DCS), and Universal Mobile Telephone System (UMTS)
applications. Wireless Local Loop (WLL) and Industrial, Scientific,
Medical (ISM) applications are also supported.
This small, power-efficient PA has a full 1700 to 2200 MHz
bandwidth coverage packed into a single compact package. All
active circuitry in the module is contained in a single Gallium
Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC).
The CX65105 is manufactured with Skyworks Aluminum (Al) GaAs
Heterojunction Bipolar Transistor (HBT) process, which allows for
single supply operation while maintaining high efficiency and
good linearity.
The 8-pin Leadless Chip Carrier (LCC) device package and pinout
are shown in Figure 1. Figure 2 shows a functional block diagram
for the CX65105. Signal pin assignments and functional pin
descriptions are provided in Table 1.

DATA SHEET • CX65105
1. Connect a +5.0 V supply voltage to VCC1 and VCC2, and
+3.6 V supply voltage to VREF. If available, enable the current
limiting function of the power supplies to 1.0 A for the +5.0 V
supply current and 30 mA for the +3.6 V supply current.
2. Connect a signal generator to the RF signal input port. Set it to
the desired RF frequency at a power level of 7 dBm or less to
the Evaluation Board but do NOT enable the RF signal.
3. Connect a spectrum analyzer to the RF signal output port.
4. Enable the power supply.
5. Enable the RF signal.
6. Take measurements.
CAUTION: If the input signal exceeds the rated power, the
CX65105 Evaluation Board can be permanently
damaged.

Notes:
1) Pin 9 provides both a thermal and electrical ground.
This ground path is critical and must be as short
as possible.
2) Transmission line lengths T1 and T2 should be
minimized.
