RFFM7600
Theory of Operation and Applications
The RFFM7600 is a single-chip integrated front end module (FEM) for high performance LTE DL and WiMAX applications in the
2.5GHz to 2.7GHz ISM band. The FEM greatly reduces the number of external components minimizing footprint and assembly
cost of the overall LTE TDD and 802.16e solution. The RFFM7600 has an integrated linear power amplifier, a power detector,
and Tx filtering and a switch, which is capable of switching between Rx and 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 LTE DL and WiMAX RF systems. As the RFFM7600 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 con-
figurations. 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 RFFM7600 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 RFFM7600 can be used as power monitor in the system. All inputs and out-
puts are internally matched to 50.
Transmit Path
The RFFM7600 has a typical gain of 34dB from 2.5GHz to 2.7GHz, and delivers >27dBm typical output power in WiMAX and
>24dBm typical in LTE DL with ACP <-45dBc The RFFM7600 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 RFFM7600 contains a low pass filtering (LPF) to attenuate the 2nd Harmonics to -38dBm/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.
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.
RFFM7600 Biasing Instructions to the Eval board:
• WiMAX or LTE DL Transmit:
www.DataSheet.co.kr
• 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 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 mea-
sured 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 RFFM7600 evaluation board can be permanently dam-
aged.
• To turn off FEM, turn off RF power of signal generator; then PDOWN, VREG and VCC.
