The STMicroelectronics STW82100B is an integrated down converter providing 8 dB of gain, 10.5 dB NF, and a very high input linearity by means of its passive mixer.
The STMicroelectronics STW82100B is an integrated down converter designed for cellular infrastructure equipment and other wireless communication systems. It provides 8 dB of gain, a noise figure of 10.5 dB, and high input linearity (IIP3: +25.5 dBm). The device embeds two wide-band auto-calibrating VCOs and an integer-N synthesizer, suitable for both receiver and transmitter requirements.
The STW82100B features an integrated RF balun with internal matching, allowing a direct 50 ohm single-ended interface to the RF port. It includes an embedded DAC with dual current output to drive an external PIN diode attenuator, reducing the need for discrete components. The device operates over a temperature range of -40°C to +85°C in a 44-lead VFQFPN package.
