Page | 1 Revised: November 30, 2022 Bluetooth Low Energy BLE 4.2 Radio PCBA Model Number: RADMEDIA-BLE-T21, RADMEDIA-BLE-T22 User Manual Description Page | 2 Revised: November 30, 2022 RADMEDIA-BLE-T21 BLE PCBA utilizes the Nordic nRF52810-QCAA SoC with a PCB trace antenna. RADMEDIA-BLE-T22 BLE PCBA utilizes the Nordic nRF52811-QCAA SoC with a PCB trace antenna. The nRF52811 BLE SoC is simply a slightly newer version of the nRF52810 BLE SoC and provides the exact same radio functionality. RADMEDIA-BLE-T21/RADMEDIA-BLE-T22 operates as a ‘Connectable-Beacon’ and transmits its beacon information at a fixed interval that can be adjusted from 1 to 2.2seconds and at a Tx power of 0dBm. For the nRF52810-QCAA and nRF52811-QCAA SoC, refers to the nRF52810/nRF52811 Product Specification and the SDK is available from the Nordic Semiconductor website. Main Features - Complete Bluetooth® low energy SoC (4.2 specification) - 32-bit ARM Cortex-M4F processor @ 64MHz - Size : 32pin QFN 5x5x0.85mm - Operating Frequency : 2,402MHz ~ 2,480MHz - Up to 24kB SRAM and 192kB Flash - Certified for FCC and Bluetooth - Rx sensitivity : Typical -93dBm - Operational Temperature range : -20°C to 70°C - CR2477 primary coin cell - Red and Green visual indicators(LED’s) - Optional MEMs accelerometer Applications - Asset Tracking - Remote Monitoring Page | 3 Revised: November 30, 2022 The (Family model RADMEDIA-BLE-T21/RADMEDIA-BLE-T22) two models of Main Board share the same PCB layout. The only difference is the RADMEDIA-BLE-T22 uses a slightly newer BLE SoC in the nRF52811-QCAA. ⚫ RADMEDIA-BLE-T21 uses the nRF52810-QCAA BLE SoC ⚫ RADMEDIA-BLE-T22 uses the nRF52811-QCAA BLE SoC Model Item Description Placement Type/ Model Manufacturer Name Manufacturers.

PCB Antenna Bandwidth One way of measuring the bandwidth after the antenna is implemented on a PCB and connected to a transmitter is to write test software that steps a carrier across the frequency band of interest. By using the maximum hold function on a spectrum analyzer, the variation in output power across frequency can easily be measured. Figure 9 shows how the output power varies on the IFA when the PCB is horizontally oriented and the receiving antenna has horizontal polarization. This measurement was not performed in an anechoic chamber, thus the graph shows only the relative variation for the given frequency band. Figure 9. Bandwidth of PCB Antenna 4.

Suchfiles are includedin CC2430DBreferencedesign[1]. The gerberfile is calledInverted_F_Antenna.spland the DXFfile is calledInverted_F_Antenna.dxf.If the antennais implementedon a PCBthat is widerthanthe antenna,avoidplacingcomponentsor havinga ground planecloseto the end pointsof the antenna.If the CADtool beinguseddoesnot supportimportinggerber or DXFfiles,see Figure1 and Table1. The antennaimpedanceis tunedto 50 ohmon the referenceboard.The impedancewill howeverbe affectedby differentsize and shapeof the groundplane,objectsin the antennanearfieldsuchas mechanicalassemblies(housing,batteries,etc.),PCBthickness,PCBmaterialand so on. It is therefore recommendedto add a pi-networkcloseto the antennafeedpointfor impedancematching.
