Product details

Overview

BAR 64-07 E6327 from Infineon Technologies is a silicon PIN diode optimized for high-frequency RF switching and attenuator applications up to 6 GHz. It delivers very low capacitance (0.17 pF at 0 V, 1–1.8 GHz), low forward resistance (2.1 Ω @ 10 mA), and high reverse voltage rating (150 V), enabling precise signal control in cellular front-end modules and microwave switches.

For engineers reviewing the BAR 64-07 E6327 datasheet, BAR 64-07 E6327 pinout, BAR 64-07 E6327 application, or BAR 64-07 E6327 equivalent, key selection criteria include RF insertion loss (0.16 dB @ 1.8 GHz, 10 mA), isolation (17 dB @ 1.8 GHz), thermal resistance (R_thJS ≤ 290 K/W), and SOD323 package compatibility with high-density RF layouts.

Technical Context

The BAR 64-07 operates as a current-controlled RF resistor: forward bias modulates its series resistance (rf = 0.85–2.1 Ω across 1–100 mA), while reverse bias maintains ultra-low capacitance (≤0.17 pF) for minimal signal loading. Its I-region width (50 µm) and carrier lifetime (1550 ns) are tuned for fast switching with low distortion in 50 Ω systems.

Designed for series configuration in RF paths, it supports DC blocking and AC signal routing without external bias networks. Its AEC-Q101 qualification confirms suitability for automotive RF modules requiring stable performance from –55 °C to +125 °C ambient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PIN diode RF switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMV1232-079LF	Higher C_T (0.25 pF @ 0 V, 1 GHz); lower V_R (30 V); SOT-23 package.	Better suited for sub-3 GHz consumer IoT, not automotive or high-voltage RF.	Select when cost sensitivity outweighs 150 V rating and ultra-low capacitance needs.
BAP64-03W	Same SOD323 package; higher R_thJS (370 K/W); lower I_F max (50 mA).	Limited to low-power receive-path switching; unsuitable for high-duty-cycle Tx paths.	Choose only for receive-only functions where thermal margin is less critical.

Compared with SMV1232-079LF and BAP64-03W, BAR 64-07 E6327 uniquely combines 150 V standoff, 0.17 pF capacitance, and AEC-Q101 qualification-making it the only option for thermally constrained, high-reliability automotive and infrastructure RF switches.

FAQ

What is the maximum RF frequency range supported by BAR 64-07 E6327?

The BAR 64-07 E6327 is characterized and specified for operation from 1 MHz up to 6 GHz. Its ultra-low capacitance (0.17 pF) and low forward resistance (2.1 Ω) ensure stable RF performance across this full band, with measured insertion loss and isolation data validated at 1.8 GHz, 2.45 GHz, and 5.6 GHz.

Does BAR 64-07 E6327 require external bias circuitry for RF switching?

No external bias circuitry is required beyond a simple series current-limiting resistor. The device operates as a current-controlled RF resistor: forward bias current (1–100 mA) directly sets its RF series resistance, enabling direct drive from microcontroller GPIO or dedicated bias ICs without active regulation.

Is BAR 64-07 E6327 suitable for pulsed RF applications?

Yes - its permissible pulse load curves confirm safe operation at IF_max/IF_DC ratios up to 10× for pulse widths ≥10 µs (D = 0). This supports radar pulse modulation and burst-mode wireless protocols without thermal runaway, provided average power remains within 250 mW limits.

How does the SOD323 package affect PCB layout for RF performance?

The SOD323 footprint minimizes parasitic inductance and capacitance due to short lead lengths and symmetric pad geometry. To preserve RF integrity, designers should use 50 Ω microstrip routing, ground vias adjacent to both pads, and avoid solder mask over the RF path - all validated in Infineon's reference layouts for BAR64-series devices.
