专利汇可以提供Interdigital preamplifier专利检索，专利查询，专利分析的服务。并且A bandpass preamplifier for isolating a narrow frequency band, especially in the VHF or UHF range, from interference or out-ofband radiation generated by high energy transmitters operating at frequencies near the desired band. The circuit includes a first turnable combline bandpass filter, employing strip line inductive elements, which provides a narrow band input to a field effect transistor amplifier. A second similar filter receives the amplified signal and furnishes a very narrow band output signal characterized by very strong attenuation of out-of-band interference.，下面是Interdigital preamplifier专利的具体信息内容。

权利要求

1. An interdigital preamplifier comprising: radio frequency amplifying means; first filter circuit means coupled to said amplifying means for applying a bandpass input signal thereto, said first circuit means including at least one resonant circuit, said resonant circuit being comprised of a strip line inductive element having a capacitive element coupled thereto; second filter circuit means coupled to said amplifying means for receiving a bandpass output signal therefrom, said second filter circuit means including at least one resonant circuit, said resonant circuit comprised of a strip line inductive element having a capacitive element coupled thereto; and, housing means including top and bottom portions, said strip line inductive elements coupled at both ends thereof to said housing means and arranged in parallel configuration, said top and bottom portions of said housing means forming upper and lower ground planes with respect to said strip line inductive elements.

2. An interdigital preamplifier as in claim 1, wherein: said first and second filter circuit means each include a plurality of said resonant circuits.

3. An interdigital preamplifier as in claim 2, wherein: said capacitive elements included in said plurality of resonant circuits are adjustable, whereby said first and second filter circuit means are tunable to a selected frequency pass band.

4. An interdigital preamplifier as in claim 2, wherein: said first and second filter circuit means each include at least one resonant circuit having a strip line inductive element of a first structural configuration, and at least one resonant circuit having a strip line inductive element of a second structural configuration.

5. An interdigital preamplifier as in claim 2, wherein: said first and second filter circuit means each include at least one resonant circuit having a strip line inductive element of tubular configuration, and at least one resonant circuit having a strip line inductive element comprised of a pair of metalized strips.

6. An interdigital preamplifier as in claim 1, wherein: said strip line inductive elements are imprinted on etched printed circuit boards.

7. An interdigital preamplifier as in claim 2, wherein: said radio frequency amplifying means includes a field effect transistor.

8. An interdigital preamplifier as in claim 7, wherein: said field effect transistor is arranged in common gate configuration.
