RF evaluation and development kits, boards and components are essential tools for testing, evaluating and developing radio frequency (RF) systems. This article will discuss the 106137-HMC370LP4 application field and working principle.

The 106137-HMC370LP4 is a digital step-tunable voltage-controlled oscillator (VCO). This component operates in the frequency range of 2.7 to 4 GHz, and covers a tuning range of 200 MHz. It features an integrated precision Varactor that exhibits low temperature coefficient and good linearity, and guarantees low phase noise performance. Besides, it needs only one external resistor to control the voltage-control frequency.

The 106137-HMC370LP4 is mainly used for wireless applications such as transceivers, radio-frequency identification (RFID) systems, cellular telecommunication, handsets, and wireless local area network (WLAN) transceivers. It is also suitable for direct conversion receivers, channel filters, and loop delay oscillators (LDOs).

The working principle of the 106137-HMC370LP4 is based on the fact that the frequency of a VCO is a function of the voltage applied to its varactor diode. By varying this voltage, it is possible to tune the output frequency of the VCO. The 106137-HMC370LP4 is designed to be driven by an0 external tuning voltage. This voltage is applied to the tail node of the VCO circuit to control the frequency of the VCO.

The 106137-HMC370LP4 has an integrated reference buffer that generates an oscillating output signal and provides a DC bias current. The reference buffer is also responsible for setting the current of the PLL VCO core. This ensures that the VCO operates within its stable frequency range, thereby reducing phase noise. The PLL can be used in applications such as frequency multiplication, frequency division, and locking of an internal VCO to an external reference.

Furthermore, the 106137-HMC370LP4 has an integrated power amplifier (PA) and can be used in applications that require high amplification. The PA is designed to operate in the frequency range of 2.7 to 4 GHz, and provides up to 20 dB of gain with good linearity. This makes it ideal for amplifying signals with an output power of up to +27 dBm.

In summary, the 106137-HMC370LP4 is a versatile component that is designed to meet the requirements of various RF applications. It features an integrated precision varactor that exhibits low temperature coefficient and good linearity, which guarantees low phase noise performance. Additionally, the integrated reference buffer and PA allow the 106137-HMC370LP4 to be used in a variety of applications such as frequency multiplication, frequency division, and signal amplification.
