Pentek Inc. has released the latest member of its Bandit family of RF modules that accepts RF signals over the range of 400MHz to 4GHz. According to the firm, the Model 7120 2-channel analog RF tuner amplifies, filters and downconverts RF signals to an IF signal suitable for A/D conversion by any of several Pentek signal acquisition modules. The device is packaged in a shielded PMC/XMC module with front panel connections for easy integration into RF systems without the use of an external tuner.

The 7120 accepts RF signals on two front panel SSMC connectors. Low noise amplifiers are provided along with two programmable attenuators allowing downconversion of input signals ranging from -60dBm to -20dBm in steps of 0.5dB. The Model 7120 input frequency is programmable across the 400-4000MHz band with a tuning resolution of less than 100KHz.

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 10MHz reference from either a front panel reference input, or from or an on-board 10MHz oven controlled crystal oscillator, which provides an exceptionally precise frequency standard with excellent phase noise characteristics.

Output is provided as baseband I and Q at bandwidths up to 390MHz. Alternatively, either the I or Q output can be used as a real IF output signal. User provided output IF filters support custom output bandwidths for specific application requirements. Because of the gain, filtering and translation provided by the 7120, the output is well-matched to the A/D inputs of high-performance signal acquisition products from Pentek, including the Cobalt and Onyx families.

The Model 7120 is a shielded PMC/XMC form factor module designed to be integrated on a host carrier for power. The module features a MicroUSB port for programming the input tuning frequencies, gain and reference clock selection. Penteks ReadyFlow board support package includes the necessary programming support for the Model 7120.

The Model 7120 PMC/XMC module is designed for air-cooled, conduction-cooled and rugged operating environments. It is available as a 3U/6U Compact PCI (Models 7220/7320/7420), 3U VPX (Model 5220), PCIe (Model 7820) and AMC (Model 5620).
