Forward Path

The operational gain of the BLE100 amplifiers is 34 dB with 16 dB of return loss. The operating gain includes provisions for the insertion loss of the input cable equalizer and required reserve gain to operate the Bode equalizer in the middle of its range. The low-noise figure, pre-amplifier stage, is a 1 GHz hybrid followed by a power-doubled output stage. Between the two stages is a JXP-*B pad socket, the Bode board, and the flatness and equalizer board. Because these losses are located interstage, the noise figure is only significantly impacted by the insertion loss of the forward cable equalizer or broadband cable simulator, and the input pad if its value is increased from zero.

Figure 2-7 illustrates the interconnection among these components:

Return Path

The circuit board of the BLE100 includes the return path. This equips the BLE100 to pass signals in the return or upstream direction. The standard circuit board contains all components including the diplex filters with extended return bandwidth for the amplifier input and output.

Optional SRE-*-* return equalizers compensate for cable attenuation and are available in 1 dB increments for S-split, and 2 dB increments for all other splits, from 0 dB through 12 dB.
