SKY85742-11中文资料5 GHz, 802.11n/ac Front-End Module数据手册Skyworks规格书

描述 Description

The SKY85742-11 is a highly-integrated, 5 GHz front-endmodule (FEM) incorporating a 5 GHz single-pole, double-throw(SPDT) transmit/receive (T/R) switch, a 5 GHz low-noiseamplifier (LNA) with bypass, and a 5 GHz power amplifier (PA)intended for mobile/portable 802.11n/ac applications andsystems.

An enable/disable function is included that allows power savingsduring off mode. An integrated logarithmic power detector with20 dB of dynamic range is included to provide closed-loop powercontrol within the system when operating in either high powermode or power save mode.

The device is provided in a compact, 16-pin, 2.3 x 2.3 x 0.33 mm Quad Flat No-Lead (QFN) package.

特性 Features

• Fully matched, with integrated 5 GHz PA, LNA with bypass mode, and SPDT switch

• Transmit gain: 29 dB
• Receive gain: 13 dB
• Output power: +18.5 dBm, MCS7, HT20
• Output power: +17.5 dBm, MCS9, VHT80
• Small QFN (16-pin, 2.3 x 2.3 x 0.33 mm) package (MSL1, 260 °C per JEDEC J-STD-020)

简介

SKY85742-11属于RF/IF射频/中频RFID的射频前端（LNA+PA）。由制造生产的SKY85742-11射频前端（LNA + PA）本系列中的产品是各种集成电路，其中集成了射频 (RF) 信号链连接到系统天线的部分中常见的一种或多种功能，如低噪声放大器 (LNA) 和可编程放大器 (PA)。任何给定器件所含的实际功能各不相同，相比旨在提供更高应用灵活性的器件，针对相对较窄应用的器件通常集成更大一部分必要的信号链。
