The emergence of a new class of millimeter wave (mmW) chips is an essential step for network operators wanting to roll out 5G coverage. Supporting the high data rates enabled by 5G systems will require mmW frequencies. The industry is converging on three major mmW bands, namely, 24/26 GHz, 28 GHz/ and 37/39 GHz. Further, active antenna ICs will be required to control gain, phase control and beam forming in the frequency bands.

At IMS 2018, Anokiwave – a provider of IC-based, mmW active antenna solutions – introduced a family of 5G Gen-2 active antenna ICs at all three mmW bands. This introduction was part of the company’s plan to commercialize 5G mmW systems with silicon chips. Specifically, the AWMF-0139 operates at 24.25 – 27.5 GHz, the AWMF-0157 operates at 26.5 – 29.5 GHz and the AWMF-0156 operates at 37.1 – 40.0 GHz (see Figure 1).

All of these chips contain a highly integrated silicon quad core that is tailored for 5G phased array applications. Each chip supports 4 radiating elements, and includes gain and phase controls for analog RF beam steering. The company’s IP blocks enable low-cost hybrid beam forming with high energy efficiency and 5G fast beam steering (see Figure 2).

The 5G-Gen2 chips are highly integrated silicon ICs packaged in wafer level chip scale packages (WLCSP), easily fitting within the typical 5.77 mm lattice spacing at 26 GHz, 5.3 mm lattice spacing at 28 GHz, and 3.8 mm lattice spacing at 39 GHz.

The company’s chips come at an opportune time when several challenges face the development of 5G networks. First, development in the microwave and millimeter wave frequency bands will be different from typical RF type systems. Second, phased arrays – essential elements for 5G development – have been used for many years in the aerospace and defense markets but are relatively new to the commercial world. Finally, many companies want to participate in the upcoming 5G boom but a significant portion of them are relatively new to the market.

Anokiwave’s family of 5G-Gen2 ICs will address all of these challenges by providing a starting platform for developers to begin evaluating and understanding mmW frequencies and phased array performance. Further, the company is in full-volume production with both our first-generation and second-generation parts, highlighting the maturity of their chips.


Anokiwave offers evaluation kits for ease of adoption of the technology and capabilities. The kits include boards with the IC, USB-SPI interface module with drivers, and all required cables. Pilot production deliveries are available now.
