The AV132-315 is a voltage controlled variable attenuator from Alpha’s series of HIP3™ components. It is specifically designed and specified for use as a wide dynamic range low distortion attenuator for DCS and PCS base station applications centered at 1837.5 MHz and 1960 MHz. The AV132-315 employs a monolithic quadrature hybrid and a pair of silicon PIN diodes to achieve the specified low distortion performance. It operates from 0–12 V with 1.6 mA typical control current at maximum attenuation. The AV132-315 is packaged in a small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.

*23 dB Attenuation Range
*1.5 dB Insertion Loss, 1.5 SWR
*0–12 V Control Voltage
*43 dBm IP3
*Small Footprint LGA Package
*Designed for DCS/PCS Base Station Applications

Product Description
 The RF3133 is a high-power, high-efficiency power amplifier module with integrated power control.
The device is self-contained with 50Ω input and output terminals.
The power control function is also incorporated, eliminating the need for directional couplers, detector diodes, power control ASICs and other power control circuitry; this allows the module to be driven directly from the DAC output.
The device is designed for use as the final RF amplifier in GSM850, EGSM900, DCS and PCS handheld digital cellular equipment and other applications in the 824MHz to 849MHz, 880MHz to 915MHz, 1710MHz to 1785MHz, and 1850MHz to 1910MHz bands.
On-board power control provides over 37dB of control range with an analog voltage input; and, power down with a logic “low” for standby operation.

* Complete Power Control Solution
* Single 2.9V to 5.5V Supply Voltage
* +35dBm GSM Output Power at 3.5V
* +33dBm DCS/PCS Output Power at 3.5V
* 55% GSM and 52% DCS/PCS ηEFF

Typical Applications
* 3V Quad-Band GSM Handsets
* Commercial and Consumer Systems
* Portable Battery-Powered Equipment
* GSM850, EGSM900, DCS/PCS Products
* GPRS Class 12 Compatible

This product is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals splitband surface acoustic wave (SAW) transmit filters.
Since the rejection is provided by a single filter, no switches are required, saving board space
and external components, eliminating switch loss, and reducing programming complexity.
In typical cellular phone architectures, the transmit filter fits between the driver amplifier and the
power amplifier. This filter reduces the noise in the Rx band being amplified by the transmit chain, enhancing receiver sensitivity. High rejection keeps unwanted signals out of the receive path.
Avago’s thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters at a fraction of their usual size.
