This application is a divisional of U.S. Non-Provisional Application No. 10/214,097 filed Aug. 8, 2002, now allowed. U.S. Non-Provisional Application No. 10/214,097 claims the benefit of U.S. Provisional Application No. 60/312,086 filed Aug. 15, 2001, and U.S. Provisional Application No. 60/363,545, filed Mar. 13, 2002. U.S. Non-Provisional Application No. 10/214,097, U.S. Provisional Application No. 60/312,086, and U.S. Provisional Application No. 60/363,545 are incorporated herein by reference.
Features and advantages of the present invention include the integration of an active splitter tuner arrangement onto a single IC, having a relatively small physical size and footprint, in order to drive multiple tuners.
This particular technique is also effective to improve second and third order distortion product performance by using a differential circuit topology. The technique of the present invention also provides AGC for associated amplification modules by providing the gain control function integrated with the amplification module. Finally, the present invention facilitates full use of the cable signal range with little or no noise figure penalty while also reducing space requirements, reducing costs, and easing the manufacturability cable set-top boxes.
Each of the second stage 1520 of the modules 1408, 1410, and 1412 is driven by the high gain amplifier 1502 of the first stage device 1404.
Similarly, each of the second stage amplifiers 1522 is driven by the low gain amplifier 1504 of the first stage device 1404. The gain of the second stage amplifiers 1520 and 1522 can be independently controlled, and the amplifiers are used to selectively combine signals output from the amplifiers 1502 and 1504. In other words, the second stage amplifiers 1520 and 1522 can be used to switch in or out the first stage amplifiers 1502 and 1504. This feature provides the amplification module 1402 with the ability to vary its gain smoothly without effecting its overall linearity.
6. The amplifier of claim 2, wherein the number of second signals is representative of predetermined frequency spectrum; and
