RF-to-Digital μModule Receivers

February 1, 2011

Linear Technology (Milpitas, CA) has introduced the LTM9004 and LTM9005, two RF-to-digital μModule® receivers that integrate the key components for 3G and 4G base station receivers (WCDMA, TD-SCDMA, LTE, etc.) and smart antenna WiMAX base stations. The integrated μModule receivers offer a dramatic reduction in board space, integrating the RF mixer/demodulator, amplifiers, passive filtering and 14-bit, 125Msps ADCs in one conveniently small package. The LTM9004 implements a direct conversion architecture with an I/Q demodulator, low-pass filter and a dual ADC. The LTM9005 implements an IF-sampling architecture with a downconverting mixer, SAW filter and a single ADC.
