Section 5.1.7 on Cryogenics added, and Evaluation Receiver General section 5.1.8 added. Summary The receiver development plan consists of two distinct efforts. One will result in a receiver suitable for the evaluation of the first antenna. The specifications for these receivers are given in Table 5.1 and the principal milestones in Table 5.2. Table 5.1 Specifications for The Evaluation Receivers.
All bands are dual linear polarization.
Some components will be similar or identical and efforts will be made to design the receivers in such a way that some parts of the design will be transferable to the production receivers. However the focus of the effort will be to produce in a timely manner a receiver system that is suitable for the initial tests. This will involve the use of many components identical to those used on the present 12m receivers. The evaluation receivers will be equipped with three frequency bands. All receivers will be dual channel receiving orthogonal linear polarizations.
