Product specification
UHF linear push-pull power transistor
BLV857
Fig.10 Printed-circuit board and component lay-out for 860 MHz class-A test circuit.
Dimensions in mm.
The components are situated on one side of the copper-clad epoxy fibre-glass board, the other side is unetched and serves
as a ground plane. Earth connections from the component side to the ground plane are made by through metallization.
