RFX8053 Advanced Data Sheet CMOS 5GHz WLAN 802.11ac RFeIC with PA, LNA and SPDT GND ANT NC CTL 16 15 14 13 Description PDET 1 12 RXEN VDD 2 11 RX VDD 3 10 NC NC 4 9 VDD 5 6 7 8 TX GND TXEN GND RFX8053 is a highly integrated, single-chip, single-die RFeIC (RF Front-end Integrated Circuit) which incorporates key RF functionality needed for IEEE 802.11a/n/ac WLAN system operating in the 5.15-5.825GHz range. The RFX8053 architecture integrates a high-efficiency high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in a CMOS single-chip device. RFX8053 has simple and low-voltage CMOS control logic, and requires minimal external components. A directional coupler based power detect circuit is also integrated for accurate monitoring of output power from the PA. RFX8053 is assembled in an ultra-compact low-profile 2.5x2.5x0.45 mm(Max) 16-lead QFN package. With support to direct battery operation, the RFX8053 is ideal RF front-end solution for implementing 5GHz WLAN in smartphones and other mobile platforms.

Note 2: If control voltage can exceed 1.8V, a 1KΩ – 10KΩ series resistor is recommended for the application circuit on each control line. Note 3: Thermal measurements were performed on an RFaxis test EVB under typical use conditions. Please contact RFaxis for details regarding the test conditions and the configuration of the thermal vias on the EVB. Refer to “PCB Land Pattern” for recommended thermal vias. 3 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com RFX8053 Advanced Data Sheet TRANSMIT PATH CHARACTERISTICS (VDD=3.6V; T=+25 oC) Parameters Units Min Operating Frequency Band GHz 5.15 Linear Output Power for 802.11ac dBm +16.5 Linear Output Power for 802.11n Typ Max Conditions 5.825 +17 EVM -35dB, 802.11ac, MCS9, VHT80 dBm +18 EVM -32dB, 802.11n, MCS7, HT40 Linear Output Power for 802.11a dBm +19 EVM 3.5%, 802.11a, QAM64, 54 Mbps Linear Output Power for 802.11a 6Mbps dBm +21 For 802.11a 6Mbps Mask Compliance Small-Signal Power Gain dB 28 Between TX and ANT pins Gain Flatness dB +/-1 Between 5.15 – 5.85 GHz TX Quiescent Current mA 210 TX Linear Current mA 270 POUT = +18dBm Out-of-Band Rejection dBc -10 -15 At 3.9 – 7.2 GHz, relative to in-band gain Power Detector Voltage Output mV 300 Second Harmonic dBc -35 POUT=+19dBm, CW Third Harmonic dBc -50 POUT=+19dBm, CW Input Return Loss dB -10 At TX Port Output Return Loss dB -10 At ANT Port Load VSWR for Stability (CW, Fix Pin for Pout=+21dBm with 50Ω load) N/A 4:1 6:1 All non-harmonically related spurs less than -43dBm/MHz Load VSWR for Ruggedness (CW, Fix Pin for Pout=+21dBm with 50 Ohm Load) N/A 8:1 10:1 No Damage 1600 POUT = +5 to +20dBm, 10kΩ Load 4 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com RFX8053 Advanced Data Sheet RECEIVE PATH CHARACTERISTICS (VDD=3.6V; T=+25 oC) Parameters Units Min GHz 5.15 Gain dB 10 Noise Figure Operating Frequency Band Typ Max Conditions 5.85 All RF Pins are Loaded by 50Ohm 12 High Gain Mode, Between ANT and RX pins; RXEN= High, CTL=Low dB 3.1 High Gain Mode, At ANT Pin Insertion Loss for LNA Bypass Mode dB 5 Between ANT and RX Pins; RXEN=Low, CTL=Low -6 At ANT Port, High Gain Mode Input Return Loss dB -10 Bypass Mode -6 At RX Port, High Gain Mode -8 Bypass Mode Output Return Loss dB RF Port Impedance Ohm DC Quiescent Current 50 16 No RF Applied, Through VDD, High Gain Mode 0.003 No RF Applied, Through VDD, Bypass Mode +6 At ANT Pin, High Gain Mode +20 At ANT Pin, Bypass Mode mA IIP3 dBm CONTROL LOGIC TRUTH TABLE TXEN CTL RXEN Mode Of Operation 0 0 0 Receive Bypass Mode 0 0 1 Receive Mode, High-Gain 1 X 0 Transmit Mode All Others Note: Not Specified “1” denotes high voltage state (> 1.2V) “0” denotes low voltage state (<0.3V) at Control Pins “X” denotes don’t care, high or low state 1KΩ – 10KΩ series resistor may be required for each control line 5 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com RFX8053 Advanced Data Sheet PACKAGE DIMENSIONS (All Dimensions in mm): PCB LAND PATTERN PACKAGE MARKING (With Recommended Thermal Vias) 0.2mm 0.5mm 0.25mm 0.45mm Pin 1 Mark 1.6mm 1.6mm 8053 First Line: Part Number LLL.L Second Line: Lot Number BYWW Third Line: Date Code 0.25mm drill (x9) 3.0mm 0.55mm 2.5mm 6 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com
