Product details
Overview
ADG936BCP-500RL7 from Analog Devices is an absorptive dual SPDT RF switch optimized for wideband operation up to 4 GHz, delivering 36 dB off-isolation at 1 GHz, 0.9 dB insertion loss at 1 GHz, and CMOS/LVTTL-compatible control logic with single 1.65 V to 2.75 V supply. It serves as a matched RF signal routing element in antenna diversity and transceiver front-end designs.
For engineers reviewing the ADG936BCP-500RL7 datasheet, ADG936BCP-500RL7 pinout, ADG936BCP-500RL7 application, or ADG936BCP-500RL7 equivalent, key selection criteria include absorptive port termination (50 Ω shunt), 20-lead LFCSP package footprint, sub-14 ns switching times, −40°C to +85°C industrial temperature range, and RF performance validated to 1 GHz with guaranteed isolation and return loss specs.
Technical Context
The ADG936BCP-500RL7 implements two independent absorptive SPDT switches using a CMOS process, each with 50 Ω terminated shunt legs to ensure stable VSWR regardless of switch state. Its on-board CMOS control logic accepts 1.65 V–2.75 V logic levels and eliminates external level-shifting circuitry.
It operates across dc to 4 GHz (−3 dB bandwidth), maintains ≥31 dB off-isolation up to 1 GHz, and achieves ≤1.25 dB insertion loss at 1 GHz under 2.5 V supply. Video feedthrough is limited to 3 mVp-p, and third-order intercept (IP3) reaches 27.5 dBm at 900 MHz, supporting low-distortion RF routing in ISM-band systems.

FAQ
What is the RF bandwidth supported by the ADG936BCP-500RL7?
The ADG936BCP-500RL7 supports RF operation from dc to 4 GHz (−3 dB bandwidth), with specified performance-including insertion loss, isolation, and return loss-guaranteed up to 1 GHz. Its absorptive architecture maintains consistent 50 Ω port matching across this full range, making ADG936BCP-500RL7 suitable for multiband ISM, Bluetooth, Zigbee, and early 5G FR1 front-end applications.
Is the ADG936BCP-500RL7 pin-compatible with the ADG936BRU-500RL7?
No, ADG936BCP-500RL7 and ADG936BRU-500RL7 are not pin-compatible. ADG936BCP-500RL7 uses a 20-lead 4 mm × 4 mm LFCSP (CP-20-6) package with exposed thermal pad, while ADG936BRU-500RL7 uses a 20-lead TSSOP (RU-20) package. Pin numbering and physical layout differ significantly; PCB redesign is required when substituting between these variants of ADG936BCP-500RL7.
Does the ADG936BCP-500RL7 require external DC blocking capacitors?
No, the ADG936BCP-500RL7 supports true dc-coupled RF operation and does not require external DC blocking capacitors on any RF port. Its internal architecture allows direct connection of dc-biased RF sources or loads-reducing component count, insertion loss, and board area. This capability is confirmed in the General Description and Applications sections of the ADG936BCP-500RL7 datasheet.
What is the maximum RF input power the ADG936BCP-500RL7 can handle?
The ADG936BCP-500RL7 has a 1 dB compression point (P–1 dB) of 16 dBm at 1000 MHz and supports up to 16 dBm input power with 0.5 V dc bias (per Table 1). Absolute maximum RF input power is rated at 18 dBm. Exceeding these limits risks distortion, gain compression, or permanent damage-so system-level power budgeting must respect ADG936BCP-500RL7's specified RF handling capability.
How does the absorptive architecture of the ADG936BCP-500RL7 improve system-level RF performance?
The absorptive architecture of ADG936BCP-500RL7 terminates OFF-state RF ports with 50 Ω resistive loads, ensuring stable VSWR (<1.5:1) regardless of switch state. This prevents reflected energy from disrupting upstream components-such as power amplifiers or LNA input stages-and improves overall signal integrity in sensitive receive paths. Unlike reflective switches, ADG936BCP-500RL7 eliminates the need for external matching networks in most applications.
