LDD211G6103A-095 is a RF filter widely used in radio frequency circuits. It is an important component in wireless communication systems and radar systems for providing frequency selective isolation and noise reduction. This article covers the application field and working principle of the LDD211G6103A-095.

Application Field

The LDD211G6103A-095 is a high frequency bandpass filter with 3dB passband of 1.30 to 1.45GHz. It is designed to reject out-of-band interference while allowing a desired frequency band to pass through. It can be used in a range of wireless communication systems, such as cellular, PCS, WCDMA, GSM-EDGE, and HiperLAN for improved system sensitivity and selectivity. It can also be utilized in high-resolution imaging radar systems such as long-range surveillance, navigation, and meteorology.

Working Principle

The LDD211G6103A-095 RF filter operates by using surface wave acoustic technology to create a bandpass filter. The filter combines interdigital transducers and multiple surface acoustic wave reflectors into a single structure. The interdigital transducers create the propagating surface acoustic wave which is then reflected by the reflectors. Variations in the thickness of the metal layers, length of the reflector, and the distance between the reflecting surfaces can be used to tune the filter. The filter provides low insertion loss, high out-of-band rejection, and excellent linearity. It is also highly temperature stable. The filter allows for positive control over the center frequency, signal bandwidth, and phase of the passband signal.

The LDD211G6103A-095 RF filter is an ideal choice for high frequency and wireless communication systems and is capable of providing excellent performance and noise reduction. Its excellent temperature stability makes it an ideal choice for long-range radar systems, such as navigation, meteorology, and surveillance. It is capable of providing high out-of-band rejection while allowing the desired frequency band to pass through, making it a great choice for high-resolution imaging radar. It is also a great choice for cellular, PCS, WCDMA, GSM-EDGE, and HiperLAN wireless communication systems in providing frequency selective isolation and noise reduction.
