Abstract
The utility model relates to a power frequency divider, when the power frequency divider matches with an OTL amplifier, the frequency response of the power frequency divider can be improved, and the utility model doesn't influence hyperfrequency response a little. In the utility model, a direct current isolating capacitor is connected in series with the input end or the output end of a lowpass filtering circuit of the existing power frequency divider. The utility model is used for improving the frequency response of the OTL amplifier.
Description
The utility model is about frequency divider.
Employed OTL amplifier in sound appliances at present, its LF-response depends on the capacity of its output capacitance, the big more LF-response of capacity is good more, so just need with big capacity electrochemical capacitor, and big capacity electrochemical capacitor has bigger inductance composition, can produce phase shift by frequency signal, and frequency is high more obvious more, so this amplifier can not be taken into account the high and low frequency response.Present power divider should not play the improvement effect to the frequency response of OTL amplifier when being used with the OTL amplifier.
The purpose of this utility model is to improve the LF-response of OTL amplifier with novel power divider, and does not therefore influence its high frequency response.
The utility model is achieved in that the input of the low-pass filter circuit of present power divider or output serial connection capacitance is promptly constituted novel power divider.The output capacitance of OTL amplifier is removed the back directly to be connected with novel power divider.This connection still can make the direct current composition in the OTL amplifier output current not enter load, be so available big capacity electrochemical capacitor do capacitance with the low frequency response that improves the OTL amplifier because of, avoided of the influence of the inductance composition of big capacity electrochemical capacitor again to medium-high frequency.
The OTL amplifier is connected the LF-response of promptly improving the OTL amplifier as stated above with novel power divider do not influence its high frequency response again, and method is simple.
Accompanying drawing is the circuit theory diagrams of embodiment
Among the figure 1,2nd, the output capacitance C1 of the input C:OTL amplifier of novel power divider, C2 are frequency division electric capacity L1, and L2 is the frequency division inductance
The utility model embodiment: an end of frequency division inductance (L2) is connected with input (1), and the end that (C) held in an end of the other end and frequency division electric capacity (C2) and the transmission of electricity of OTL amplifier is connected.The other end of frequency division electric capacity (C2) is connected with input (2).
Claims (1)
1. novel power divider, one end of frequency division inductance (L2) is connected with input (1), the other end is connected with an end of frequency division electric capacity (2), the other end of frequency division electric capacity (C2) is connected with input (2), it is characterized in that: an end of the output capacitance of OTL amplifier (C) is connected with the tie point of frequency division electric capacity (C2) with frequency division inductance (L2).
