Product Specification PE64102 UltraCMOS® Digitally Tunable Capacitor (DTC) 100–3000 MHz General Description The PE64102 is a DuNE™-enhanced digitally tunable capacitor (DTC) based on pSemi’s UltraCMOS® technology. DTC products provide a monolithically integrated impedance tuning solution for demanding RF applications. They also offer a linear capacitance change versus tuning state and excellent harmonic performance compared to varactor-based tunable solutions. This highly versatile product can be mounted in series or shunt configurations and uses a 3-wire (SPI compatible) serial interface. It has a high ESD rating of 2 kV HBM on all ports making this the ultimate in integration and ruggedness. The DTC will be offered in a standard 12-lead 2.0 x 2.0 x 0.55 mm QFN commercial package. pSemi’s DuNE™ technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOS® process, providing performance superior to GaAs with the economy and integration of conventional CMOS.

Page 5 of 13 PE64102 Product Specification Serial Interface Operation and Sharing bits are clocked and only maintains the last 8 bits it received. 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 15. 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 PE64102 is controlled by a three wire SPIcompatible interface. As shown in Figure 14, 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 14. 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 Figure 14.

Page 7 of 13 PE64102 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. 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. CP1 and CP2 represent 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. 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. Figure 16. Equivalent Circuit Model Schematic Table 7.

Maximum Operating RF Voltage Condition Limit VP to VM 6 VPK VP to RFGND 6 VPK VM to RFGND 6 VPK 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. ©2018–2021 pSemi Corporation All rights reserved.

Page 9 of 13 PE64102 Product Specification Evaluation Board Figure 17. Evaluation Board Layout The 101-0700 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 Shunt (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 Shunt configuration (J4, J5). 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 (0.036 mm).
