High Frequency Ceramic Solutions Application Note: AN020 Date: 03/19/2015 M.Carmona/I.Johnson Application Note for Nordic Semiconductor's CSP package: nRF51822-CEAA, nRF51822CDAB, nRF51822-CFAC, nRF51422-CEAA, nRF51422-CDAB, nRF51422-CFAC chipsets using Johanson's Integrated RF Front End Solution Impedance Matched Balun Filter (BPF) Abstract The nRF51822-CEAA, nRF51822-CDAB, nRF51822-CFAC, nRF51422-CEAA, nRF51422-CDAB, nRF51422-CFAC devices from Nordic Semiconductor are powerful, highly flexible, multiprotocol SoCs designed for Bluetooth® low energy, ANT, and 2.4 GHz ultralow power wireless applications. The devices are built around an ARM® Cortex™ CPU and integrate fully compliant Bluetooth low energy and ANT stacks. The devices also include a rich selection of analog and digital peripherals such as ADC, serial interfaces, PWM, and quadrature demodulator - that can be used in a wide range of ultra-low power applications. 1.9mm This application note describes how to use Johanson Technology’s 2450BM08B0003 balun-filter, shares active measured results obtained with the chipsets, provides design files for ease of use on any PCB/Application environment and RF technical support contact info at Johanson Technology. Introduction In partnership with Nordic Semiconductor, Johanson Technology has developed an 5-pin LGA EIA 0604 (1.4mmx1.0mmx0.69mm) ceramic passive device that contains the following functions: -Differential complex impedance (X+jY) matching network for the nRF51x22-CxAx CSP family chipsets -Differential to 50Ω single-ended balun -Specifically designed BPF to pair with the nRF chipsets for FCC/ETC (+Korea, Japan, China) emissions compliance This front-end 5-pin device considerably reduces implementation size area by using smaller effective PCB real estate usage. Also, it reduces component count, eliminates RF variability (100% RF tested before T&R), and offers excellent temperature stability (4ppm). AEC-Q200 available.
