At frequencies below the series resonance frequency, the MLCC can be represented by an equivalent circuit as shown in Fig.14. In general, the quantities C, ESR and L are frequency dependent. For most applications, C and L can be regarded as frequency independent below 1 GHz. C * Dependent on the size of the capacitor and is approximately: - 0.6 nH for case size 0603 - 1 nH for case sizes 0805 and 1206 (these figures are accurate to within 20%). Because of the inductance L, associated with the MLCC, there will be a frequency at which the inductive reactance will be equal to the reactance of the capacitor. This is known as the series resonance frequency (SRF) and is given by: SRF = 1 2 LC At the SRF, the MLCC will appear as a small resistor. The transmission loss through the MLCC at this series resonance frequency will be low. L MEA609 C = capacitance. ESR = equivalent series resistance which is determined by the energy dissipation mechanisms (in the dielectric material as well as in the electrodes). L = equivalent series self-inductance. Fig.14 Equivalent series representation of an MLCC. The impedance (Z) is given by: Z = The equivalent series selfinductance L is: * Independent of the dielectric material ESR 1 - (2f)2 LC + ESR 2jfC The quality factor (Q) is given by: Q = 1 - (2f)2 LC 2fESRC The frequency region above the SRF is difficult to model using lumped elements and should be described in terms of a network of transmission lines. The behaviour of the MLCC in this frequency region can be best described in terms of scattering or `s' parameters. Knowing these parameters, one can predict the response of a network accurately. There are four scattering parameters for a two-port network: s11, s12, s21 and s22: s11 is the reflection coefficient at the input port with the output port terminated in a 50 load. s12 is the reverse transmission coefficient in a 50 system. s21 is the forward transmission coefficient in a 50 system. s22 is the reflection coefficient at the output port with the input port terminated into a 50 load. When comparing the insertion loss (i.e. s21) of an MLCC at high frequencies with that of an ideal capacitor, parallel resonances above the SRF are observed. In series or shunt connections parallel resonances are usually detrimental to the operation of the circuit. They may be the cause of unacceptable insertion loss or parasitic oscillations of amplifiers. For the microwave series, we specify that the first parallel resonance frequency lies above 2 GHz and the second above 3 GHz. It is found that the typical insertion loss at the first resonance frequency is more than a factor 5 smaller than at the second resonance frequency. Using the values of C, L (= 1 nH) and the ESR at a specific frequency (f), two often used quantities can be derived. 2003 Jul 21 Rev.4 10 www.yageo.com Phycomp Product specification Surface-mount ceramic multilayer capacitors Microwave: Class 1, NP0, NME 50 V The high frequency behaviour of our CMCs is measured in a strip line configuration as shown in Fig.15 using a test fixture with the following features: air CMC * Microstrip structure (dielectric: Al2O3; thickness: 0.635 mm) * Suitable for the TRL calibration method * De-embedding for the lowfrequency range (up to 3 GHz).
