The HMC1027BG is a high performance, wideband, double balanced mixer that is part of the RF Misc ICs and Modules category of components. It has low power consumption, low noise and excellent linearity. It also offers high port-to-port isolation. The device is primarily used in applications such as Frequency Synthesizers, up/down/cross converters, test equipment and general purpose mixers.

The HMC1027BG provides high dynamic performance with an excellent noise figure (~7.0 dB @ 3 GHz), very high linearity (+10 dBm typical IP3) and low harmonic distortion (-30 dBc typical 3rd order IMD at 5 MHz signal separation). It also provides -10 dB of port-to-port isolation (@2GHz) and an exceptionally low DC power consumption (19 mA @ +5 V). The device has a built-in HCMOS/SPI compatible control logic for setting the integrated VOA, a current Mode logic (CML) output buffer and a reference bias outlet.

The device is implemented using GaAs HBT technology, allowing for high power operation and robustness. To ensure that a wide range of applications can benefit from its excellent performance, the device can couple both low level (2.5mW) and high level (30dBm) inputs to its double balanced mixers.

Its working principle centers around its double balanced mixer. This ensures that stray signals, such as noise, are rejected by the large signal-to-noise ratio of the mixer. The device typically connects two signal sources into two antenna pairs, and this gives it its excellent port-to-port isolation. Additionally, the output of the mixers can drive both low to high power circuits, such as amplifiers, synthesizers and down-converters.

The HMC1027BG is a versatile solution in the RF Misc ICs and Modules category. It has a wide frequency range, low noise factor, high linearity and good port-to-port isolation, making it suitable for various applications. Its integration of CML buffers, VoA and reference bias outlets, combined with its low power consumption and double balanced mixer, are noteworthy features that make the HMC1027BG a reliable and economical option for RF signal conversion.
