Product Description
RF5605 is a 1x1 MIMO module that is intently specified to address IEEE
802.11b/g/n WiFi 2.4GHz to 2.5GHz customer premises equipment (CPE) applica-
tions. The module has an integrated three-stage linear power amplifier, Tx harmonic
filtering and SPDT switch. The RF5605 has fully matched input and output for a
50system and incorporates matching networks optimized for linear output power
and efficiency. The RF5605 is housed in a 6mm x 6mm laminate.

• To receive WiFi set the switch control lines per the truth table.
General Layout Guidelines and considerations:
For best performance the following layout guidelines and considerations must be followed regardless of final use or configura-
tion:
1. The ground pad of the RF5605 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 decou-
pling capacitors to provide better isolation between each VCC line.
RF5605 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 RF5605 could be permanently
damaged.
