  • PLL and injection locked PLL (ILPLL) operations of a push-pull self oscillating mixer (SOM)
    Resonator consists of an abrupt varactor (Cov/C3v = 2, COV= 9.2 pF) and a 7.15 nH inductor (Q = 63 @ 500 MHz ).
  • Interference minimisation of antenna-to-range interface for pattern testing of electrically small antennas
    … constructed [3] at the National Physical Laboratory (NPL) for measurement at frequencies of 400 MHz and above. The chamber has shielded room dimensions of 7.15 m long 6.25 m high 6.25 m wide, whose inner surfaces are fully lined with 45 cm long TDK polyethylene foam pyramidal absorber. … experimental results relating to the radiation pattern measurements of an electrically small dielectric resonator antenna (DRA) were …
  • Lasers
    Problem 7.15 What is the approximate angular divergence of the output beam from a He–Ne laser (operating at 6328 Å) having a 1 m long confocal cavity? … 16 The Gaussian beam coming out of a 100 cm long symmetric spherical resonator oscillating at a … Problem 7.17 Consider a He–Ne laser with Doppler broadened linewidth of 1700 MHz .
  • A reduced-size silicon micromachined high-Q resonator at 5.7 GHz
    Fig. 12 presents an OC measurement where the reso- nant frequency was 5.78 GHz, the insertion loss was 7.15 dB, and the bandwidth was 81 MHz . RESULTS FOR THE CAVITY RESONATOR WITH BST .
  • Nanoscience
    For example, a radio-frequency (10–30 MHz ) nanomechanical resonator with a typical mass of ∼ 10−12 g has xSQL = 10−14m, only a little larger than the size of an atomic nucleus. 7.1 and [ 7.15 ]).
  • Beam Instrumentation and Diagnostics
    The layout of such a system is shown schematically in Fig. 7.15 . Especially the λ/4- resonator deflecting system requires roughly 800 mm (λ/4 of 108 MHz ≈ 750 mm).
  • Circuits and Systems for Wireless Communications
    on the circuit parameters can be obtained from Eq. ( 7.15 ), whereas a more precise estimate can be obtained from Eq. (7.12). To perform controlled experiments, a 78 MHz Colpitts os- cillator is constructed as shown in Fig. 7 … The choice of the oscillation frequency was made to be sufficiently low to allow values of the res- onator inductor and capacitors to be much higher than board-level parasitics, and yet sufficiently high so that the conclusions from the measurements can …

    … High-level servo control option • High-level mechanism monitor • Communication may be via TDA1301/SAA7345 compatible bus or I2C-bus • On-chip clock multiplier allows the use of 8.4672, 16.9344 or 33.8688 MHz crystals or ceramic resonators . Extra functions are controlled by use of ‘shadow’ registers (see Section 7.15 .3).
