Four RF additions to Renesas portfolio serve macro base transceiver stations

Four RF devices have been introduced by Renesas Electronics, for traditional macro base transceiver stations. They include the F4482/1, claimed to be the first quad-channel TX variable gain amplifiers (VGAs), the F011x family of dual-channel, first-stage, low noise amplifiers (LNA). In addition there is the F1471 RF driver amplifier, claimed to be the first high-power pre-driver with P1dB of over 1/2W, and the fourth addition is the F2934 RF switch with higher isolation in a smaller package for digital pre-distortion (DPD) feedback path.

The F4482/1 VGAs have a frequency range of 400 to 2800MHz and integrate a Balun, a low pass filter, an amplifier and digital step attenuators on a single die. They also feature Renesas’ Zero Distortion technology for enhanced quality of service with increased dynamic range, and Glitch-Free technology to protect power amplifier assembly and to simplify DPD implementation.

The dual-channel F011x are first-stage LNAs (balanced LNA or two-channel LNA), with an RF range of 650 to 2700MHz. They are characterised by a low noise figure of 0.55dB at 2600MHz with low return loss (-27dB input, -23dB output).

The high-linearity F1471 RF driver amplifier has an RF frequency range of 400 to 4200MHz with 17dB gain. It also has OIP3 up to +38dBm and OP1dB of 28.5dBm at 2600 MHz, with adjustable OIP3 performance and DC bias.

The SP2T F2934 RF switch has a frequency range of 50 to 6000MHz and a high isolation (70dB at 1GHz and 2GHz, 74dB at 3GHz and 67dB at 4GHz). It is in a small (3.0 x 3.0mm) QFN package to minimise PCB real estate requirements. It also has Renesas Kz Constant Impedance technology to maintain VSWR during switching transition.

All are designed to provide the high performance, high reliability, flexibility, and smaller form factor demanded by 5G macro base transceiver station systems. They all perform well across a wide range of environmental conditions and frequency bandwidths, says Renesas.

“As the 5G transition picks up speed, we have upgraded our macro base transceiver station portfolio of receive and transmit chain components with higher performance and higher integration,” said Naveen Yanduru, vice president of RF Communications, Industrial and Communications at Renesas. The new devices address the complete RF signal chain and enable customers to be 5G-ready as they bring their next-generation macro base transceiver station systems to market, he added.

The devices can be combined with the company’s F1490 high-gain RF amplifier and integrated F0443 RX VGA for a complete RF signal chain, advises Renesas.

The F4482/1, F011x, F1471, and F2934 devices are available now.
