TELEDYNE MICROWAVE SOLUTIONS NF v1 Ka‐Band (29‐31GHz) BUC with Integrated Linearizer (TSA‐214144) Summary This is a Ka‐Band Block Up‐Converter (BUC) with an integrated IF Linearizer that is designed to generate 29‐30GHz or 30‐31GHz from a 1‐2GHz IF Band. The output band is selected via an RS‐ 422 command, as is gain control, mute, and reference frequency selection. The RS‐422 interface also allows reporting of the input power to the mixer, internal temperature, and local oscillator (LO) lock detect. The unit uses a fully integrated IF Linearizer ASIC which can be used to linearize a Teledyne Microwave Solutions SSPA. As this uses an intelligent adaptive technique, SSPAs from other manufacturers may also be linearized. The achievable improvement in linearity depends on the type of SSPA, modulation scheme, and symbol rates used (measured improvement for a TMS amplifier is shown in Figure 2). Feedback of the RF signal is required to utilize the RF linearizer: approximately +10dBm is required at the RF feedback input.
