RF5605
Theory of Operation and Applications
Overview
The RF5605 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 RF5605 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 RF5605 is fully RF matched to 50 internally and requires minimal external compo-
nents, it is very easy to implement on to PCB designs. To reduce the design and optimization process on the customer applica-
tion, 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 RF5605 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 RF5605 can be used as power monitor in the system. All inputs and outputs are internally matched to
50 .
Transmit Path
The RF5605 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 RF5605 requires a single positive of 5.0V to operate at full spec-
ifications. The VREG pin requires a regulated supply at 2.85V to maintain nominal bias current.
Out of Band Rejection
The RF5605 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 Harmon-
ics 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 Inser-
tion loss of 0.8dB and 30dB (typical) isolation to Tx port.
RF5605 Biasing Instructions to the Eval board:
• 802.11b/g/n Transmit:
• 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.
• Bias VCC to 5.0V first with VREG=0.0V. If available, enable the current limiting function of the power supply to 1100mA.
• 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.
• Turn on VREG to 2.85V (typ.).
• On VREG (of Eval board), regulated supply is recommended. Be extremely careful not to exceed 3.0V on the VREG pin or the
part may exceed device current limits.
• 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.
• 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 RF5605 Evaluation Board can be permanently dam-
aged.
• To turn off FEM, turn off RF power of signal generator; then PDOWN, VREG and VCC.
