Linear Technology LT5515
The LT5515 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature generator. 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. These outputs can interface directly to channelselect filters (LPFs) or to a baseband amplifier.| Part No. | LT5515 |

● DESCRIPTIO Frequency Range: 1.5GHz to 2.5GHz High IIP3: 20dBm at 1.9GHz High IIP2: 51dBm at 1.9GHz Noise Figure: 16.8dB at 1.9GHz Conversion Gain: –0.7dB at 1.9GHz I/Q Gain Mismatch: 0.3dB I/Q Phase Mismatch: 1° Shutdown Mode 16-Lead QFN 4mm × 4mm Package with Exposed Pad The LT ®5515 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. In an RF receiver, the high linearity of the LT5515 provides excellent spur-free dynamic range, even with fixed gain front end amplification. Channel filtering can be performed directly at the outputs of the I and Q channels. LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
