HMC380QS16GE

RF mixers are a type of nonlinear electronic device used to modulate or demodulate various electrical signals. In particular, they are used to convert signals between baseband frequencies and radio frequencies. They are a fundamental component in many mobile, radio and communication systems. The HMC380QS16GE is a combination analog multiplier and 6th-order elliptic lowpass filter and is specifically designed for wideband mixer applications.

This product is packaged in a 3 x 3mm DFN package which offers a low cost and dense solution for numerous applications. The HMC380QS16GE is manufactured using Hittite’s advanced GaAs MMIC process and provides excellent linearity and low noise figure (NF) performance.

The HMC380QS16GE is well suited for a wide range of applications. It can be used in I/Q mixing, up-conversion/down-conversion, frequency generation, signal modulation/demodulation, and wideband signal amplification. Furthermore, it is ideal for numerous applications such as cellular/3G/LTE transceivers, WLL transceivers, wifi systems, navigation systems, satellite receivers, GPS systems, and CATV systems.

The working principle of the HMC380QS16GE is based on the principles of incoherent or \'quadrature\' mixing. Quadrature mixing, also known as ‘quadrature modulation’, is the process of combining two signals in quadrature in order to obtain a desired signal. The HMC380QS16GE performs this process using two inputs, the I/Q inphase (I) and quadrature (Q). When signals are mixed using the HMC380QS16GE, they are passed through a passive diode network which mixes the signals together to create the desired signal.

The HMC380QS16GE also features 6th-order output filtering to reduce the out-of-band unwanted signals. This feature ensures that the desired signal is not distorted or impacted by unwanted signals. Additionally, the HMC380QS16GE includes both the RF and DC signals, resulting in very low level of noise and high level of dynamic range.

The HMC380QS16GE is a highly versatile and efficient mixer for numerous applications in the RF and communication fields. Its combination of quadrature mixing and 6th-order output filtering ensures that the desired signal is neither distorted nor impacted by unwanted signals. Furthermore, its small size and low cost make it an attractive solution for a wide range of applications.
