Datasheet

Pentek has today introduced a new 2-channel analog RF tuner. Accepting RF signals over the range of 400 MHz to 4 GHz, the 7120 RF tuner amplifies, filters and downconverts them to an IF signal suitable for analog-to-digital conversion. An expansion of the existing Bandit RF tuner product line, the 7120 is specifically designed for communications, radar and signal intelligence applications.

The 7120 features wider RF input signal frequency coverage, wider IF output bandwidths, improved noise figure and higher channel density. These features mean that the new RF tuner offers communications, radar and signal intelligence customers a new solution to their system requirements at an affordable price.

An optional five-stage lowpass or bandpass input filter can be specified with several available frequency and attenuation characteristics for RF image rejection and harmonic suppression.

The Model 7120 includes a programmable low noise LO frequency synthesizer. It accepts a 10 MHz reference from either a front panel reference input, or from or an on-board 10 MHz oven controlled crystal oscillator, which provides an exceptionally precise frequency standard with excellent phase noise characteristics.

The model 7120 accepts RF signals on two front panel SSMC connectors, while input frequency is programmable across the 400 to 4000 MHz band with a tuning resolution of less than 100 KHz. Low noise amplifiers are provided along with two programmable attenuators allowing downconversion of input signals ranging from -60 dBm to -20 dBm in steps of 0.5 dB. Designed for air-cooled, conduction-cooled and rugged operating environments, the model 7120 PMC/XMC module is available as a 3U/6U Compact PCI (Models 7220/7320/7420), 3U VPX (Model 5220), PCIe (Model 7820) and AMC (Model 5620).

The Model 7120 starts at $4,995 USD. Oscillator and connector options for PMC or XMC are available. Delivery is 8 to 10 weeks ARO.
