ZH8770N

产品介绍

ZH8770N is a highly integrated RF Front-End integrated circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax/be WLAN systems operating in the 5.925-7.125GHz range. It integrates a high-efficiency, highlinearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

ZH8770N provides an excellent heat dissipation environment for Wi-Fi 7 network equipment which have multiple RF paths configuration. It achieves ultra-low power consumption while providing a competitive EVM level when cooperates with the DPD algorithm. A DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.

ZH8770N is assembled in a compact, low-profile 3x3x0.75mm 16-lead QFN package, which is an ideal RF Front-End solution for implementing 6GHz highpower WLAN systems supporting multiple standards including 802.11a/n/ac/ax/be.
