Application Information
The RMPA5251 can be optimized to work over 2 frequency ranges, 4.9 to 5.35 GHz (Low Band) and 5.15 to 5.85 GHz (High
Band).
Using the 2 external component configurations described on the next page, the RMPA5251 can be optimized to give the
best EVM, power and gain over a specified bandwidth.
The data on sheets 7–9 shows the performance when the evaluation board is configured for either low or high band
performance.
