The transistor is encapsulated in a
4-lead, SOT121 flange envelope, with
a ceramic cap. All leads are isolated
from the flange.
A marking code, showing gate-source
voltage (VGS) information is provided
for matched pair applications. Refer
to the 'General' section for further
information.

referred to the according level of either the equal amplified tones. Related to the according peak envelope power
these figures should be decreased by 6 dB.
Ruggedness in class-AB operation
The BLF177 is capable of withstanding a load mismatch
corresponding to VSWR = 50 through all phases under the
following conditions:
VDS = 50 V; f = 28 MHz at rated output power.

The circuit and components are situated on one side of the epoxy fibre-glass board, the other side being fully
metallized to serve as earth. Earth connections are made by means of hollow rivets, whilst under the source
leads and at the input and output copper straps are used for a direct contact between upper and lower sheets.
