These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.

Becker Nachrichtentechnik GmbH
Software-Defined Radio (SDR) is an attractive approach for mobile communication architectures in the development and evaluation phase for a rapid prototyping on a flexible platform. SDRs support a wide frequency range. However, for practical use in the field the HF properties are insufficient. The transmit power is limited to a 2-digit mW value. Dedicated filters are required for an effective suppression of out-of-band signals and to improve the noise figure of the receiver chain. Extending SDRs with application-specific RF-frontends achieves optimal RF performance in the field.
