Low Noise Voltage Controlled Oscillators
The SMV0978L is intended for the 902-928 MHz ISM band and will find uses in amateur radio, location and monitoring services, radar, and radio-frequency identification tags. This rugged oscillator operates off a 3 V DC source while drawing less than 6 mA, typically, and provides the end user nominally 4 dBm of output power into a 50 Ω load. The technology utilized in the SMV0978L enhances the product's output frequency stability with respect to supply voltage variations (pushing) and output loading variations (pulling). The pulling specification for the SMV0978L is less than 5 MHz/V with a 14 dB return loss, any phase, while pushing is less than 3 MHz within a 5% change of the supply voltage.
The SMV0978L comes in Z-Communications' SUB-L surface mount package measuring 0.30× 0.30× 0.08. This VCO is ideal for automated surface mount assembly and reflow. It is available in tape and reel packaging for production requirements.
