“…A varactor diode, rather than a fixed capacitance, provides the variable phase shift. In [12], we found that a ±20% capacitance variation yielded a 400 MHz shift in the filter frequency response, which represents a tuning bandwidth of about 10%. In [13], the same approach was implemented using a reflection-type analog phase shifter and Lange couplers.…”

This two-part paper presents a representative sample of recent advances in microwave active filter design. In the second part, we discuss design techniques for tunable structures and frequency control. First, we present switchable and continuously-tunable bandstop filters employing MMIC negative resistances to compensate for losses. Next, we detail several approaches to the design of tunable high-order "recursive-like" filters. Layouts and measurements are given for different MMIC implementations, with simulated results presented in other instances. Finally, we discuss new technologies and processes for future low-cost, low-noise microwave MMIC active functions. The article concludes with the description of a development, including experimental results, of frequency-control techniques based on locked-loop architectures.

An active recursive filter approach is proposed for the implementaion of an inductorless, tuneable RF filter in BiCMOS. A test circuit was designed and manufactured in a 0.35 m SiGe BiCMOS technology. In simulations, the feasibility of this type of filter was demonstrated and reasonably good performance was obtained. The simulations show a center frequency tuning range from 6 GHz to 9.4 GHz and a noise figure of 8.8-10.4 dB depending on center frequency. Gain and Q-value are tunable in a wide range. Simulated IIP-3 and 1-dB compression point is -26 dBm and -34 dBm respectively, simulated at the center frequency 8.5 GHz and with 15 dB gain. Measurements on the fabricated device shows a center frequency tuning range from 6.6 GHz to 10 GHz, i.e. slightly higher center frequencies were measured than the simulated.
