Power amplifier with modulation function 3MHz to 1.2GHz

Power amplifier with modulation function 3MHz to 1.2GHz

With high gain, it can increase the output power of any tracking generator up to a maximum of 5W.

The TBMDA3 wideband power amplifier with modulation capability is designed to create a low-cost signal source for immunity testing of electronic building blocks and products. It is intended to be driven by the tracking generator output of a spectrum analyzer. Its high gain allows it to boost the output power of any tracking generator up to 5W. The TBMDA3 is ideal for driving Tekbox near-field probes to find sensitive spots in electronic circuits, or for generating electric fields of up to 550V/m when driving the Tekbox TEM cell TBTC0, 300V/m when driving TBTC1, and 100V/m when driving TBTC2 or TBTC3. The test signals for immunity testing can be modulated in CW, AM, or PM. As a result, the TBMDA3 provides built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, the TBMDA3 can also generate a 217 Hz signal with a 12.5% duty cycle to simulate mobile phone TDMA noise.

Power amplifier with modulation function 50KHz to 70MHz

Power amplifier with modulation function 50KHz to 70MHz

In the input power range of 5 dBm to 0 dBm, the output power of the tracking generator can be boosted up to a maximum of 5W.

The TBMDA4 modulated wideband power amplifier is designed to create a low-cost signal source for immunity testing of electronic building blocks and products, driven by the output of a spectrum analyzer's tracking generator. It can boost the output power of the tracking generator up to 5W within an input power range of -5 dBm to 0 dBm. It ideally complements the TBMDA3, which covers a frequency range of 10 MHz to 1 GHz from 100 kHz to 50 MHz. The TBMDA4 is ideal for driving Tekbox near-field probes to find sensitive spots in electronic circuits, creating electric fields of up to 550 V/m when driving the TEM cell TBTC0, and 300 V/m when driving TBTC1. When driving TBTC2 or TBTC3, it generates 100 V/m. The test signals for immunity testing can be CW, AM, or PM modulated, providing built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, the TBMDA4 can also generate a 217 Hz signal with a 12.5% duty cycle to simulate mobile phone TDMA noise.

Wideband Voltage Amplifier (DHPVA Series)

Wideband Voltage Amplifier (DHPVA Series)

The 100/200MHz DHPVA is a high-frequency amplifier with variable gain.

■Even when changing the gain settings, the bandwidth (100/200MHz) remains constant, featuring excellent gain flatness, low noise, and low offset drift, making it a very high-performance amplifier. ■Since the bandwidth remains constant even with different gain settings, the rise time of the pulse hardly changes (within ±10%). ■Ideal for accurate and reliable time-resolved measurements. ■Adopts a multi-stage design, allowing for the avoidance of using multiple amplifiers that could lead to dynamic limitations.

High-Speed Gain Fixed Current Amplifier (HCA Series)

High-Speed Gain Fixed Current Amplifier (HCA Series)

It maintains a constant bandwidth and gain up to the specified maximum capacitance value without being affected by capacitance, frequency correction, or special connections.

In many cases where high-frequency products are used, issues such as unwanted vibrations, imperfections in ground shielding, nonlinearity, gain peaking, and bandwidth reduction due to insufficient amplifier design can arise. However, Femto's current amplifiers are designed to adequately address these problems. They prevent gain peaking, vibrations, and significant bandwidth reduction regardless of the signal's source parameters or wiring, with capacitance up to 2nF. When capacitance is a few pF, the bandwidth of high-frequency current amplifiers significantly decreases; however, Femto's high-speed current amplifiers are not affected by this limitation and can handle a wide range of capacitance. For precise offset and bias control, they come equipped with two trim pots for flexible use. Input offset current correction can be adjusted over a wide range, fully maintaining dynamics even from signals with large DC components. The bias output voltage can be adjusted within -12 to +12V using this bias trim pot.
