Abstract
A development effort is described that yielded a compact broad-band ECM module using soft and hard substrate material employing microstrip, slotline, and coplanar line. Integrated functions include coupling, limiting, upconversion, downconversion, broad-band amplification, amplitude modulation, switching, gating, and stable frequency generation. A high-level frequency converter with a + 28-dBm intercept point resulted in high dynamic range, spurious-free operation (--45 dBc). Extremely flat amplification with low-current drain is achieved with distributed and cascode FET amplifiers at S - C and X-bands.
