CXG1092N
SP5T GSM Triple-Band Antenna Switch
For the availability of this product, please contact the sales office.
Description
The CXG1092N is a high power antenna MMIC
switch for use in triple-band GSM handsets.
One antenna can be routed to either of the 2 Tx or
3 Rx ports.
20 pin SSOP (Plastic)
Features
• 4 CMOS compatible control lines
• Standby control
• 34.5dBm power handling at 5.0V (GSM900)
• Low second harmonic < –36dBm at 34.5dBm
• Small package size: 20-pin SSOP (6.4 × 5.0 × 1.25mm)
Applications
Triple-band handsets using combinations of GSM900/DCS1800/PCS1900 and DECT
Structure
GaAs J-FET MMIC (The Sony JFET process is used for low insertion loss.)
Absolute Maximum Ratings (Ta = 25°C)
• Bias voltage
VDD 7 V
• Control voltage Vctl 5 V
• Operating temperature Topr –35 to +85 °C
• Storage temperature Tstg –65 to +150 °C
Note on Handling
GaAs MMICs are ESD sensitive devices. Special handling precautions are required.
Sony reserves the right to change products and specifications without prior notice. This information does not convey any license by
any implication or otherwise under any patents or other right. Application circuits shown, if any, are typical examples illustrating the
operation of the devices. Sony cannot assume responsibility for any problems arising out of the use of these circuits.

CXG1092N
Application Note (1)
Impedance matching for harmonic minimization
To achieve the 2nd harmonic levels lower than –36dBm for GSM900
Design of 1.8GHz harmonic matching network and the 900MHz trap network is dependent on the board design
and components.

Technique
Allows use of the CXG1092N (SP5T) in handsets
with 3V min. battery voltage (2.7V SW supply).
The CXG1092N is for 5V nominal battery voltage
but work well down to 4V.
Fundamentally, the 577µs time slot waveform is
used to increase the 2.7V supply to over 4V.
∗ This waveform may be taken from the PA
ramping input (or drain supply in case of drain
power control) or via the TX ON/OFF logic.
