DS121008 RFFM4200 Theory of Operation and Applications The RFFM4200 is a single-chip integrated front-end module (FEM) for high performance WiFi applications in the 2.4GHz to 2.5GHz ISM band. The FEM greatly reduces the number of external components minimizing footprint and assembly cost of the overall 802.11b/g/n solution. The RFFM4200 has an integrated b/g/n power amplifier, a power Detector, and TX filtering and a Switch, which is capable of switching between WiFi RX, WiFi TX operations. The device is manufactured using InGaP HBT and pHEMT processes on a 6mm x 6mm x 0.95mm laminate package. The module meets or exceeds the RF front-end needs of the 802.11b/g/n WiFi RF systems. The RFFM4200 is a very easy part to implement. To reduce the design and optimization process on the customer application, the evaluation board layout should be copied as close as possible, in particular the ground and via configurations. Gerber files of RFMD PCBA designs can be provided upon request. The supply voltage lines should present an RF short to the FEM by using bypass capacitors on the VCC traces. To simplify bias conditions, the RFFM4200 requires a single positive supply voltage (VCC), a positive current control bias (VREG) supply, and a positive supply for switch control. The built-in Power Detector of the RFFM4200 can be used as power monitor in the system. All inputs and outputs are internally matched to 50Ω. Transmit Path The RFFM4200 has a typical gain of 34dB form 2.4GHz to 2.5GHz, and delivers 25.5dBm typical output power in 11n HT20 MCS7 and 26dBm typical in 11g 54Mbps. The RFFM4200 requires a single positive supply voltage of 5.0V to operate at full specifications. The VREG pin requires a regulated supply at 2.9V to maintain nominal bias current. Out of Band Rejection The RFFM4200 contains a low pass filtering (LPF) to attenuate the 2nd Harmonics to -47dBm/MHz (typical), to meet the out of band rejection requirements of the system for FCC specification. Receive Path The RX path has a 50Ω single-ended port. The receive port return loss is 9.6dB minimum. In this mode, the FEM has an Insertion loss of 0.8dB and 30dB (typical) isolation to TX port. RFFM4200 Biasing Instructions to the Evaluation Board 802.11b/g/n Transmit: 1. Connect the FEM to a signal generator at the input and a spectrum analyzer at the output. Set the Pin at signal generator is at -20dBm. 2. Bias VCC to 5.0V first with VREG=0.0V. If available, enable the current limiting function of the power supply to 750mA. 3. Refer to switch operational truth table to set the control lines at the proper levels for WiFi TX.• Turn on VREG to 2.9V (typ). On VREG (of evaluation board), a regulated supply is recommended. Be extremely careful not to exceed 3.0V on the VREG pin or the part may exceed device current limits. 4. Turn on Pdown to 2.9V (typ). PDOWN pin can be tied to VREG supply. NOTE: It is important to adjust the VCC voltage source so that +5V is measured at the board; and the +2.9V of VREG is measured at the board. The high collector currents will drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate. 5. Turn on RF of signal generator and gradually increase power level to the rated power. CAUTION: If the input signal exceeds the rated power, the RFFM4200 evaluation board can be permanently damaged. 6. To turn off FEM, turn off RF power of signal generator; then PDOWN, VREG, and VCC. 802.11b/g/n Receive: • To receive WiFi set the switch control lines per the truth table.

The ground pad of the RFFM4200 has special electrical and thermal grounding requirements. This pad is the main RF ground and main thermal conduit path for heat dissipation. The GND pad and vias pattern and size used on the RFMD evaluation board should be replicated. The RFMD layout files in Gerber format can be provided upon request. Ground paths (under device) should be made as short as possible. 2. The RF lines should be well separated with solid ground in between the traces to eliminate any possible RF leakages or cross-talking. 3. Bypass capacitors should be used on the DC supply lines. The VCC lines may be connected after the RF bypass and decoupling capacitors to provide better isolation between each VCC line. RFFM4200 TX Production and System Calibration Recommendation It’s highly recommended to follow the DC biasing step and RF power settings in the production calibration or test: 1. Connect the RF cables of input and output then connect to the proper equipment. 2. Apply VCC, then Vreg as per the data sheet recommendations. 3. Set RF input to the desired frequency and initial RF input power at -20dBm. This will insure the Power amplifier is in a linear state and not over driven. 4. Set FEM in TX mode by the truth table. 5. Apply Pdown = high 6. Sweep RF from low to high output power and take measurements at the rated output power. 7. Insure that the output power at turn on doesn’t saturate the power amplifier. The recommended output power should be about 10dB to 20dB below the rated power. Start calibrating from low to high power in reasonable steps until the rated power is reached then take the measurements. CAUTION: If the input signal exceeds the maximum input power specifications, the RFFM4200 could be permanently damaged. 6 of 15 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or [email protected].
