DATA SHEET CLA Series: Silicon Limiter Diode Bondable Chips Applications LNA receiver protection Commercial and defense radar Features Established Skyworks limiter diode process High-power, mid-range, and cleanup designs Low insertion loss: 0.1 dB @ 2.6 GHz Peak power handling to +74 dBm Ultra-low spike leakage power Tight control of I layer base width Mesa and planar chip designs Description Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of GreenTM, document number SQ04–0074. The Skyworks CLA series of silicon limiter diodes provides passive receiver protection over a wide range of frequencies from 100 MHz to over 30 GHz. These devices use the well-established Skyworks silicon technology resulting in high resistivity and tightly controlled base width PIN limiter diodes. Limiter circuits using these devices perform with strong limiting action and low loss. The CLA series consists of eleven individual chip designs of different intrinsic region base widths and capacitances designed to accommodate multi-stage limiter applications. The mesaconstructed, thin base width, low capacitance CLA4601-000, CLA4602-000, CLA4604-000, CLA4605-000, and CLA4611-000 are designed for low-level and cleanup applications. The CLA4603-000, CLA4606-000 through CLA4608-000, and CLA4610-000 are planar designs designated for high-power and mid-range applications. The CLA4609-000 thick base width mesa diode is designed for coarse limiter-stage applications.

Note 2: Pulsed power measurements taken at 1 μs pulse width, pulse frequency = 10 kHz, and 0.1% duty cycle. Note 3: Recovery time represents the transition time from the high-loss state to the low-loss state following the removal of a high-power input. It is defined as the time from the end of the high-power pulse to the time when insertion loss has returned to within 3 dB of the quiescent (low-power) state. Note 4: Spike Leakage (ergs) = ts x Ps x 107 where ts is the spike width at the half-power point (in seconds) and PS is the maximum spike amplitude in watts.

Limiter diodes with lower capacitance values to 0.08 pF and constructed with a passivated mesa configuration are available in the CLA4601-000, CLA4602-000, CLA4604-000, CLA4605-000 and CLA4611-000 series. The mesa devices offer low capacitance and, therefore, broader bandwidth, lower loss, and faster response at reduced power. These diodes are also available in chip form and represent the ultimate in limiter performance not approached by other manufacturers. The highest power CLA4609 diodes use a mesa construction.
