Top Modulator Manufacturers in the World
A process of converting data into radio waves by adding information to an electronic or optical signal is known as a modulator. Generally, it has been applied to electromagnetic signals: radio waves, lasers/optics and computer networks. Not only that, it can even be applied to a direct current — which can be treated as a degenerate carrier wave with a fixed amplitude and frequency of 0 Hz — mainly by turning it on and off, as in Morse code telegraphy or a digital current loop interface. Here, we have mentioned the top modulator manufacturers in the world;
Analog Devices

Renesas
The Renesas Zero-Distortion™ and Glitch-Free™ pin-compatible IQ demodulator products offer the world’s lowest power consumption and the world’s lowest IM3 distortion while at the same time resulting in less than 0.5dB overshoot ringing during MSB gain transitions.
Similarly, the Renesas Zero-Distortion™ IQ modulator products provide very high IP3 and IP2 performance resulting in superb ACLR performance compared to competitive devices. The company has earned one of the top modulator manufacturers in the world.

ROHM
ROHM’s modulation is the process of converting data into electrical signals optimized for transmission. Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation, and Spread spectrum method.
This method is divided into single carrier modulation, by which the carrier occupies the entire bandwidth (i.e. amplitude, frequency, and phase), and a multicarrier scheme that modulates and transmits different data on multiple carriers. The company has earned one of the top modulator manufacturers in the world.

STMicroelectronics
STMicroelectronics’ ISOSD61 is a galvanic isolated second-order Sigma-Delta modulator based on embedded transformer coupling technology. It converts an analog input signal with a maximum range of ±320mV into a high-speed, 25 Msps, 1-bit digital data stream. The signal information can be rebuilt by means of digital filtering. The modulator is isolated from the digital I/O section through a high-speed isolated data coupling, whose performances are far better than other isolated transceivers like optocouplers.
