Preliminary Data Sheet 7 Revision 1.3, 2009-06-24
1 Features
Main features:
• Low insertion loss
• High port-to-port-isolation
• Low harmonic generation
• On-chip control logic
• High ESD robustness
• No external components required
• General purpose switch for applications up to 3 GHz
• Small leadless package TSLP-7-6
• Lead and halogen free package (RoHS and WEEE compliant)
Description
The BGS12AL7-4 General Purpose RF MOS switch is designed to cover a broad range of applications from
30 MHz to 3 GHz. The symmetric design of its single pole double throw configuration, as shown in Figure 1 offers
high design flexibility. This single supply chip integrates on-chip CMOS logic driven by a simple, single-pin CMOS
or TTL compatible control input signal. The 0.1 dB compression point exceeds the switch’s maximum input power
level of 21 dBm, resulting in linear performance at all signal levels. The RF switch has a very low insertion loss of
0.4 dB in the 1 GHz and 0.5 dB in the 2 GHz range.
Unlike GaAs technology, external DC blocking capacitors at the RF ports are only required if DC voltage is applied
externally.

2 Maximum Ratings
Attention: Stresses above the max. values listed here may cause permanent damage to the device.
Exposure to absolute maximum rating conditions for extended periods may affect device
reliability. Maximum ratings are absolute ratings; exceeding only one of these values may
cause irreversible damage to the integrated circuit.
