Name:_______________________________ EE 4002-2 Test # 2 SSN: _______________________ Spring 2004 This test is open book, and notes: 1. For the circuit below, determine the filter order, filter shape (HPF, LPF,  BPF, or BSF), and the filter type. 2. A 3 dB attenuator is placed on a network analyzer to verify that the loss is  in fact 3 dB.  The following S-parameters are observed.   What is the  actual attenuation of the device?

Unformatted text preview: Ω . 4. Using a smith chart, find the input impedance of the following circuit at 1.8 GHz. The characteristic line impedance is 50 Ω . 5. Design a biasing network for a 1 GHz BJT inverter with a bypassed R E . 6. Design a T-type matching network that transforms a Z L = 100 load to Z Ω IN = (20-j40) Ω . We wish to create a nodal quality factor of Q n = 4 with this matching network. The matching should be achieved at 600 MHz. The characteristic line impedance is 50 Ω . 7. Find the ABCD-parameters for the following three-element pi-network....
