RFFM4202
Theory of Operation and Applications
Overview
The RFFM4202 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 RFFM4202 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 and WiFi Tx operations. The device is manufactured using InGaP HBT
and pHEMT processes on a 6mmx6mmx0.95mm Laminate package. The module meets or exceeds the RF front end needs of
the 802.11b/g/n WiFi RF systems. As the RFFM4202 is fully RF matched to 50 internally and requires minimal external components, it is very easy to implement on to PCB designs. 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 RFFM4202 requires a single positive supply
voltage (VCC), a positive current control bias (VREG) supply or high impedance enable, and a positive supply for switch control.
The built-in Power Detector of the RFFM4202 can be used as power monitor in the system. All inputs and outputs are internally
matched to 50.
Transmit Path
The RFFM4202 has a typical gain of 35dB from 2.4GHz to 2.5GHz, and delivers>27dBm typical output power in 11n HT20
MCS7 and>27.5dBm typical in 11g 54Mbps with an EVM<3%. The RFFM4202 requires a single positive of 5.0V to operate at
full specifications. The VREG pin requires a regulated supply at 2.85V to maintain nominal bias current.
Out of Band Rejection
The RFFM4202 contains a low pass filter (LPF) to attenuate the 2nd Harmonics to -40dBm/MHz (typical). Depending upon the
end-user's application, additional filters may be needed to meet the out of band rejection requirements of the system. For the
system to meet FCC' s spec, a simple LC can be used between FEM and Antenna, for impedance matching and extra Harmonics attenuation to meet spec.
Receive Path
The Rx path has a 50 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.
RFFM4202 Biasing Instructions to the Eval 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 1100mA.
3. Refer to switch operational truth table to set the control lines at the proper levels for WiFi Tx. It is recommended to maintain
at least 2.85V on VTx during Tx mode. A lower VTx voltage will enable the switch in Tx mode, but 2.85V is needed to ensure
that the switch stays in Tx mode during high power peaks. Using a VTx voltage less than 2.85V in Tx mode could result in
abnormal operation or device damage.
4. Turn on VREG to 2.85V (typ).
5. 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.
6. Turn on PDOWN to 2.85V (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 +2.85V 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.
7. Turn on RF of signal generator and gradually increase power level to the rated power. CAUTION: If the input signal exceeds
the maximum rated power, the RFFM4202 Evaluation Board can be permanently damaged.
8. 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.

RFFM4202
General Layout Guidelines and considerations:
For best performance the following layout guidelines and considerations must be followed regardless of final use or configuration:
1. The ground pad of the RFFM4202 has special electrical and thermal grounding requirements. This pad is the main RF
ground and main thermal conduct 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.
RFFM4202 Tx production and system calibration recommendation:
It is 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 FEM in Tx mode by the truth table.
4. Apply PDOWN = high.
5. 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.
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 nominal input 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 rated input power
specifications, the RFFM4202 could be permanently damaged.
