TELEDYNE DEFENCE LIMITED Tuneable Bandpass Filter EB001 A Teledyne Technologies Company Features Full Comms. Bands Coverage Fast Tuning Electronically Tuneable Low Insertion Loss 8 Bit Digital Control 1MHz Resolution Applications Tactical Communications Product Description The EB001 electronically tuneable Band pass filter has been specifically designed to provide a cost effective means of accurately tuning a band pass filter over up to an octave bandwidth. Filter Control is achieved using 8 frequency control bits. With low loss and flat group delay, the EB001 is an ideal choice for tuned super-heterodyne receivers containing analogue or digital signal data. Designs are available up to 3GHz with user definable control interfaces. Designed to withstand military environments, the EB001 is a complete filter solution for military communications and commercial users who wish to reject adjacent interfering signals in agile signal environments.

(Inband) >+40 dBm (input) Tuning Control 8 bit parallel Tuning Speed 35 microsecs Input / Output Impedance 50 Ohm, standard SMA (f) VSWR @ Fo 1.5:1 Operating Temperature Range -30 to +85 degrees C Storage Temperature Range -50 to +85 degrees C DC power +5V DC at <500mA -12V to -40V DC at <1mA note 2 Size 75 x 30 x 20 mm NOTES: 1. 2. 3. Other frequency options are available. Specified performance with a –40V Bias. Option also available for –40V source to be generated internally. The linearity of the filter is directly affected by the negative bias supplied to the unit. As, standard, the unit has a P1dB (input) of +10dBm for –12V bias. Increasing the bias to –50V, the linearity and P1 will also increase to 30dBm (Input). EB001 rev 5.0 10 January 2009 Page 1 of 2
