(rfmd)) is optimized for 3.3v dc applications. for best results, the pa circuit layout fr om the evaluation board should be copied as closely as possible, particularly the gro und layout and ground vias. pin 4 must be left as a no-connect on the pcb in order for the pa to work properly. other configurations may also work, but the design process is much easier and quic ker if the layout is copied from the rf5322 evaluation board. gerber files of rfmd pcba designs can be provided on request. the rf5322 is a very easy part to implement, but care in cir- cuit layout and component selection is always advisable when designing circuits to operate at 2.5ghz. the rf5322 evaluation board layout and schematic are available using 0201 (us) size co mponents which will help shrink the overall size of the total area of the pa and components of the intended design. please contact rfmd sales or applic ation engineering for additional data and guidance. for best performance, it is important to duplicate (as closely as possible) the layout of the evaluation board. the rf5322 has primarily been characterized with a voltage on v reg of 2.8v dc . if you prefer to use a control voltage that is significantly differ- ent than 2.8v dc , or a different frequency than the recommended freque ncy range, contact rfmd sales or applications engi- neering for additional data and guidance. qfn8 package area versus other small form factor package areas an application schematic for 2.5ghz operation is included that has two additional components , one shunt inductor, and one shunt capacitor, on the output for improved second harmonic reje ction. this layout provides ~20db rejecetion at 5ghz with a minimal bom count. package type length (mm) width (mm) area (mm 2 )delta ( ? ) (mm 2 ) to qfn8 sot 23-6 3.1 3.0 9.30 4.46 qfn12 3.0 3.0 9.00 4.16 sot 23-5 2.9 2.8 8.12 3.28 qfn8 2.2 2.2 4.84 0.00
