IF Sampling Receiver
Subsystem
The LTM9005 is an IF Sampling Receiver Subsystem for
wireless base stations and communications test equip-
ment. Utilizing an integrated System in a Package (SiP)
technology, it includes a downconverting mixer, 140MHz
SAW filter, two gain stages, a variable attenuator and
analog-to-digital converter (ADC). The system is tuned for
an Intermediate Frequency (IF) of 140MHz and a signal
bandwidth of up to 60MHz; contact Linear Technology
regarding customization. The high integration and small
package allow for a very compact receiver.
The high signal level downconverting mixer is optimized
for high linearity, wide dynamic range IF sampling ap-
plications. It includes a high speed differential LO buffer
amplifier driving a double-balanced mixer. Broadband,
integrated transformers on the RF and LO inputs provide
single ended 50Ω interfaces. The RF and LO inputs are
internally matched to 50Ω from 1.6GHz to 2.3GHz.
Versions are available with ADCs up to 14-bit resolution
and 125Msps. A separate output supply allows the parallel
output bus to drive 0.5V to 3.6V logic. A single-ended CLK
input controls converter operation. An optional clock duty
cycle stabilizer allows high performance at full speed for
a wide range of clock duty cycles.
