Product speciﬁcation

UHF linear push-pull power transistor

BLV57

Conditions for Figs 11and 12:

Typical values; VCE = 25 V; IC =2 × 0,85 A; − − − Th =25 °C;  Th =70 °C; fvision = 860 MHz.

Ruggedness in push-pull class-A operation

The BLV57 is capable of withstanding full load mismatch (VSWR = 50 through all phases) under the following

conditions:

Notes

1. Three-tone test method (vision carrier

−8 dB, sound carrier −7 dB, sideband signal −16 dB), zero dB corresponds to

peak sync level.

Intermodulation distortion of input signal

≤−70 dB.

2. Two-tone test method (vision carrier 0 dB, sound carrier

−7 dB), zero dB corresponds to peak sync level.

Cross-modulation distortion (dcm) is the voltage variation (%) of sound carrier when vision carrier is switched from 0

dB to

−20 dB.

VCE = 25 V; IC =2 × 0,85 A; Th =70 °C; Po sync(1) ≤ 12,5 W; f = 860 MHz; Rth mb-h = 0,25 K/W.

At any other composition of the output signal: PL (r.m.s. value) ≤ 5 W.
