Amplifier circuit (10) for amplifying a high frequency input signal (RF In) which is, applied to the input (11) and is supplied from there to a power divider (12). The, power divider (12) is linked to the input (11) in such a way that the high frequency input signal (RF In) is divided into two partial signals RF1 and RF2 having equal power. The two partial signals RF1 and RF2 are provided at the two outputs (13) and (14) of the power divider (12). The power divider (12) is followed by a low-resistance parallel circuit made of a first amplifier block (15), which is connected to the output (13) of the power divider (12) and a second, amplifier block (16), which is connected to the second …

Why it's free to use
- Filed April 17, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 17, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 17, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
