In order to make the present utility model better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
Examples
As shown in figures 1 to 3 of the drawings,
the frequency expander comprises a first-stage power amplifier 1, a first-stage frequency multiplier 2, a second-stage power amplifier 4, a second-stage frequency multiplier 5 and a third-stage power amplifier 6, wherein the first-stage frequency multiplier 2 and the second-stage power amplifier 4 are connected through a jumper 3.
The model of the first-stage power amplifier 1 is FAP006018-20, the model of the first-stage frequency multiplier 2 is FN03027045, the model of the second-stage power amplifier 4 is FAP027045-21, the model of the second-stage frequency multiplier 5 is FN03080140, and the model of the third-stage power amplifier 6 is FAP080130-21.
The whole signal transmission flow is as follows: the power of the input signal is amplified by the first stage power amplifier 1 to drive the first stage frequency multiplier 2 to work normally. And then the output signal of the first-stage frequency multiplier 2 is subjected to power amplification through the second-stage power amplifier 4 until the second-stage frequency multiplier 4 can be driven normally to work normally. Finally, the output signal of the second-stage frequency multiplier 5 passes through the third-stage power amplifier 6 and then outputs the signal.
Specifically, the signal source output signal is fed into the first-stage power amplifier 1, and after the power is amplified by the first-stage power amplifier 1, the first-stage frequency multiplier 2 can be driven to work normally. The first-stage frequency multiplier 2 is a tripler, the first-stage frequency multiplier 2 outputs to obtain a third harmonic signal, the third harmonic signal enters into the second-stage power amplifier 4, the third harmonic signal is amplified to obtain an amplified third harmonic signal, the amplified third harmonic signal can normally drive the second-stage frequency multiplier 5 to normally work, the second-stage frequency multiplier 5 is a tripler, the signal outputs a nine-harmonic signal after passing through the second-stage frequency multiplier 5, the signal outputs to the third-stage power amplifier 6 to obtain an amplified nine-time signal, and the final output power of the signal source frequency expander is shown in fig. 3.
In order to be able to match most signal source uses, a jumper 3 connection is used between the first stage frequency multiplier 2 and the second stage power amplifier 4. If the RF signal frequency is low, the jumper is connected. The jumper wire is of a jumper wire structure commonly used in the field, and the processes of connecting and disconnecting the jumper wire are all manually operated. The signal is fed from the first stage power amplifier. If a sufficient frequency range of the signal source is used, the jumper can be disconnected and the signal fed directly from the second stage power amplifier input. The novel operating frequency range can be met simultaneously.
