RF power amplifiers

14 October 2015 Telecoms, Datacoms, Wireless, IoT

New from Freescale Semiconductor are two broadband RF power amplifiers – the Airfast AFIC901N LDMOS RF integrated device and the AFT05MS003N LDMOS transistor. The products can be operated at 3,6 or 7,5 V and are targeted for applications where power for radio range and efficiency for battery life are key design requirements.

Mobile radio systems, for instance, are transitioning from analog to digital modulation schemes, which usually requires a radio redesign. The efficiency of Freescale’s newest RF power devices allows land mobile radio OEMs to take advantage of the new transistors’ performance to enhance battery life, while their high gain provides an opportunity to reduce the number of transistors used, thus minimising system cost. Radio designers can also leverage available reference circuits to minimise time to market for their own products.

With high gain and bandwidths that cover frequency bands between 136 and 941 MHz, the devices are housed in compact and lightweight over-moulded plastic packages. Their extreme ruggedness (> 65:1 VSWR) enables highly robust handheld radios, and they are well suited for use in combination with Freescale microcontrollers for applications such as automatic meter readers that operate at 169, 434 or 868 MHz. They are also ideal for other machine-to-machine applications and supervisory control and data acquisition (scada) systems.

The AFIC901N two-stage LDMOS device delivers 1 Watt of CW of RF output power with 63% efficiency and 30 dB gain at VHF frequencies between 136 and 174 MHz. It is housed in a QFN 4 x 4 package and delivers its full 30 dBm rated power with an input power of only 0 dBm, eliminating the need for pre-amplification.

The AFIC901N offers RF matching flexibility externally to the device at the input and output, as well as at the inter-stage level. This lets designers optimise the device for their particular system requirements, including multiple radio bands, by changing only a few discrete components on the circuit board.

The single-stage AFT05MS003N provides 3 Watts of CW power and covers 136 to 941 MHz with 17 dB gain and 67% efficiency in the VHF band. It is housed in an SOT-89 over-moulded plastic package.
