Sample Board
Sample board uses RO4350 e
for circuit board. Dielectric thickness is not critical
but RFin and RFout transmission lines should be 50
ohms (w = 22 mil for thickness = 10 mil).
Solder the exposed paddle on the back of the pack-
age to the board. Proper attachment of the exposed
paddle is essential for RF and DC ground in addition
to providing a low thermal resistance.
Case temperature (Tc) is measured as shown on
the application board drawing on the top circuit
board metal as close to the body of the package as
possible.
The board must provide adequate heat sinking to
accommodate the 2.5 W typically dissipated under
small signal conditions. Sample board uses vias in
the vicinity of the ground pad to provide a suitable
heat sink connected to the ground plane of the
board as shown above.
Placement of C1, C2 and R1 are not critical but use
of 1206 for the bypass caps (C1 and C2) is critical.
