Product Details
The LT5515 is a 1.5GHz to 2.5GHz direct conversion quadrature demodulator optimized for high linearity receiver applications. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth up to 260MHz. The LT5515 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature generator.
In an RF receiver, the high linearity of the LT5515 provides excellent spur-free dynamic range, even with fixed gain front end amplification. This direct conversion receiver can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding requirements for image filtering and IF filtering. Channel filtering can be performed directly at the outputs of the I and Q channels. These outputs can interface directly to channelselect filters (LPFs) or to a baseband amplifier.
Applications
- Cellular/PCS/UMTS Infrastructure
- High Linearity Direct Conversion I/Q Receiver
- High Linearity I/Q Demodulator
- RF Power Amplifier Linearization
