The total capacitance and peak operating RF voltage are de-rated down to 1 MHz. Figure 13 shows the total shunt capacitance from 1 MHz through 100 MHz. As seen in Figure 14, the maximum RF voltage that can be placed across the RF terminals or across either RF terminal to Ground is de-rated as a function of frequency. Note: Table 1 performance specifications are not guaranteed below 100 MHz. Figures 13, 14, and 15 reflect performance of a typical PE64904. Figure 14.

Page 6 of 11 DOC-87399-1 PE64904 Product Specification Serial Interface Operation and Sharing More than 1 DTC can be controlled by one interface by utilizing a dedicated enable (SEN) line for each DTC. SDA, SCL, and VDD lines may be shared as shown in Figure 17. Dedicated SEN lines act as a chip select such that each DTC will only respond to serial transactions intended for them. This makes each DTC change states sequentially as they are programmed. The PE64904 is controlled by a three wire SPIcompatible interface. As shown in Figure 16, the serial master initiates the start of a telegram by driving the SEN (Serial Enable) line high. Each bit of the 8-bit telegram is clocked in on the rising edge of the SCL (Serial Clock) line. SDA bits are clocked by most significant bit (MSB) first, as shown in Table 5 and Figure 16. Transactions on SDA (Serial Data) are allowed on the falling edge of SCL. The DTC activates the data on the falling edge of SEN. The DTC does not count how many bits are clocked and only maintains the last 8 bits it received. Alternatively, a dedicated SDA line with common SEN can be used. This allows all DTCs to change states simultaneously, but requires all DTCs to be programmed even if the state is not changed. Figure 16.

Page 7 of 11 PE64904 Product Specification Equivalent Circuit Model Description The DTC Equivalent Circuit Model includes all parasitic elements and is accurate in both Series and Shunt configurations, reflecting physical circuit behavior accurately and providing very close correlation to measured data. It can easily be used in circuit simulation programs. Most parameters are state independent, and simple equations are provided for the state dependent parameters. The Tuning Core capacitance CS represents capacitance between RF+ and RF- ports. It is linearly proportional to state (0 to 31 in decimal) in a discrete fashion. The Series Tuning Ratio is defined as CSmax/CSmin. CP represents the circuit and package parasitics from RF ports to GND. In Shunt configuration the total capacitance of the DTC is higher due to parallel combination of CP and CS. In Series configuration, CS and CP do not add in parallel and the DTC appears as an impedance transformation network. Figure 18. Equivalent Circuit Model Schematic LS LS RS CS VM VP RF+ RFCP CP RP2 RP2 RP1 RP1 RFGND Table 8. Equivalent Circuit Model Parameters Variable Equation (state = 0, 1, 2…31) Units CS 0.129*state + 0.600 pF RS 20/(state+20/(state+0.7)) + 0.7 Ω RP1 7 Ω RP2 10 kΩ CP 0.5 pF LS 0.27 nH Table 9. Equivalent Circuit Data State Parasitic inductance due to circuit and package is modeled as LS and causes the apparent capacitance of the DTC to increase with frequency until it reaches Self Resonant Frequency (SRF). The value of SRF depends on state and is approximately inversely proportional to the square root of capacitance. The overall dissipative losses of the DTC are modeled by RS, RP1 and RP2 resistors. The parameter RS represents the Equivalent Series Resistance (ESR) of the tuning core and is dependent on state. RP1 and RP2 represent losses due to the parasitic and biasing networks, and are state-independent. Table 7.

Layout isolation is desired between all control and RF lines. When using the DTC in a shunt configuration, it is important to make sure the RF-pin is solidly grounded to a filled ground plane. Ground traces should be as short as possible to minimize inductance. A continuous ground plane is preferred on the top layer of the PCB. When multiple DTCs are used together, the physical distance between them should be minimized and the connection should be as wide as possible to minimize series parasitic inductance. The 101-0597 Evaluation Board (EVB) was designed for accurate measurement of the DTC impedance and loss. Two configurations are available: 1 Port Shunt (J3) and 2 Port Series (J4, J5). Three calibration standards are provided. The open (J2) and short (J1) standards (104 ps delay) are used for performing port extensions and accounting for electrical length and transmission line loss. The Thru (J9, J10) standard can be used to estimate PCB transmission line losses for scalar de-embedding of the 2 Port Series configuration (J4, J5). Figure 19. Recommended Schematic of Multiple DTCs The board consists of a 4 layer stack with 2 outer layers made of Rogers 4350B (εr = 3.48) and 2 inner layers of FR4 (εr = 4.80). The total thickness of this board is 62 mils (1.57 mm). The inner layers provide a ground plane for the transmission lines. Each transmission line is designed using a coplanar waveguide with ground plane (CPWG) model using a trace width of 32 mils (0.813 mm), gap of 15 mils (0.381 mm), and a metal thickness of 1.4 mils (0.051 mm).
