SPDT And SP3T Switches: Broadband Low Power
RF Micro Devices, Inc.
Ideal for general purpose switching applications requiring very low insertion loss and low power handling capability, the RF1127, a single-pole double throw switch (SPDT), and the RF1136, a single pole three throw (SP3T) switch are also suited for battery operated applications requiring high performance switching with very low DC power consumption.
RF1127 Broadband Low Power SPDT Switch
The RF1127 is a single pole double throw (SPDT) switch designed for general
purpose switching applications which require very low insertion loss
and low power handling capability. The RF1127 features low insertion
loss, good isolation, and excellent linearity performance which makes it
ideally suited for battery operated applications requiring high performance
switching with very low DC power consumption. The RF1127 builds upon
RFMD's GaAs pHEMT process and is packaged in a very compact, low profile
2 mm x 1.3 mm x 0.385 mm, leadless QFN package.
Features
- Broadband Performance Low Frequency to 3.5 GHz
- 1-Bit Control: Requires Single Control Line to Switch Between Two RF Paths
- Compatible With Low Voltage Logic (1.8 V)
- Very Low Insertion Loss: - 0.3 dB at 1 GHz (Typ.), - 0.4 dB at 2 GHz (Typ.)
- Excellent Linearity: - IIP2 > 100 dBm (Typ.), - IIP3 > 63 dBm (Typ.)
- P1dB = 23 dBm (Typ.)
- Compact Footprint
- 2.0 mm x 1.3 mm x 0.385 mm, 6-Pin, QFN

RF1136 Broadband Low Power SP3T Switch
The RF1136 is a single-pole three-throw (SP3T) switch designed for general purpose switching applications which require very low insertion loss and low power handling capability.
The RF1136 is ideally suited for battery operated applications requiring high performance switching with very low DC power consumption. The RF1136 features very low insertion loss with excellent linearity performance down to 1.8 V control voltage. Additionally, RF1136 includes integrated decoding logic, allowing just two control lines needed for switch control. The RF1136 is packaged in a very compact 2.5 mm x 2.5 mm x 0.6 mm, 12-pin, leadless QFN package.
Features
- Low Frequency - 3.5 GHz Operations
- Very Low Insertion Loss: Cell Band 0.25 dB, PCS Band 0.30 dB
- High Isolation: Cell Band 28 dB, PCS Band 22 dB
- Compatible with Low Voltage Logic: (VHIGH = 1.8 V)
IExcellent Linearity Performance(IIP2): Cell Band 110 dBm, PCS Band 110 dBm - Lowest BOM Cost and Small Solution Size: No DC Blocking Capacitors Required on the RF Paths
