F733 integrated amplifiers common emitter - common base wideband amplifier circuit

The F733 integrated wideband amplifier is a common-emitter configuration that features a total wideband amplifier with an internal feedback circuit. It is compact, offers zoom capability, and exhibits excellent circuit stability. The F733 circuit, as illustrated in the accompanying figure, utilizes an integrated wideband cascode configuration. By modifying the negative feedback resistor of the first differential amplifier, the voltage gain of the circuit can be adjusted. When terminals are shorted, the gain can reach up to 120 dB; when the terminals are shorted, the gain is limited to 40 dB. If the respective terminals are not shorted, the gain is 20 dB. The upper frequency limits for the three configurations are 40 MHz, 90 MHz, and 120 MHz.

The F733 integrated wideband amplifier is designed to deliver high performance in various applications requiring wide bandwidth and significant amplification. The common-emitter topology ensures that the amplifier can achieve high voltage gain while maintaining a linear response over a broad frequency range. The internal feedback mechanism is crucial for stabilizing the gain and minimizing distortion, which is particularly important in wideband applications where signal integrity is paramount.

The adjustable voltage gain feature allows for flexibility in system design, enabling engineers to tailor the amplifier's performance to meet specific requirements. The modification of the negative feedback resistor in the first differential amplifier stage plays a critical role in this adjustment, as it directly influences the feedback loop and, consequently, the overall gain of the amplifier.

The performance specifications indicate that the amplifier can achieve a maximum gain of 120 dB when terminals are shorted, which is suitable for applications requiring significant signal amplification. In contrast, a gain of 40 dB is achievable with a different configuration of the terminals, providing versatility in amplification settings. The gain of 20 dB when terminals are not shorted allows for moderate amplification, suitable for less demanding applications.

The upper frequency response of the F733 is noteworthy, with three distinct configurations allowing for maximum frequencies of 40 MHz, 90 MHz, and 120 MHz. This range makes the F733 suitable for various high-frequency applications, including RF amplification and signal processing in communication systems.
